Chelsea F.C.

Founding and early years (1905–1952) In 1904, English businessman Gus Mears acquired the Stamford Bridge athletics stadium in Fulham with the aim of turning it into a football ground. An offer to lease it to nearby Fulham F.C. was turned down, so Mears opted to found his own club to use the stadium. As there was already a team named Fulham in the borough, the name of the adjacent borough of Chelsea was chosen for the new club; names like Kensington FC, Stamford Bridge FC and London FC were considered. Chelsea F.C. was founded on 10 March 1905 at The Rising Sun pub (now The Butcher's Hook), opposite the present-day main entrance to the ground on Fulham Road, and were elected to the Football League shortly afterwards. Chelsea won promotion to the First Division in their second season, and yo-yoed between the First and Second Divisions in its early years. The team reached the 1915 FA Cup final, where they lost to Sheffield United at Old Trafford, and finished third in the First Division in 1920, the club's best league campaign to that point. Chelsea had a reputation for signing star players and attracted large crowds. The club had the highest average attendance in English football in ten separate seasons including 1907–08, 1909–10, 1911–12, 1912–13, 1913–14 and 1919–20. They were FA Cup semi-finalists in 1920 and 1932 and remained in the First Division throughout the 1930s, but success eluded the club in the inter-war years. Modernisation and the first league championship (1952–1983) Former Arsenal and England centre-forward Ted Drake was appointed manager in 1952 and proceeded to modernise the club. He removed the club's Chelsea pensioner crest, improved the youth set-up and training regime, rebuilt the side with shrewd signings from the lower divisions and amateur leagues, and led Chelsea to their first major trophy success – the League championship – in 1954–55. The following season saw UEFA create the European Champions' Cup, but after objections from The Football League, Chelsea were persuaded to withdraw from the competition before it started. Chelsea failed to build on this success, and spent the remainder of the 1950s in mid-table. Drake was dismissed in 1961 and replaced by player-coach Tommy Docherty. Docherty built a new team around the group of talented young players emerging from the club's youth set-up, and Chelsea challenged for honours throughout the 1960s, enduring several near-misses. They were on course for a treble of League, FA Cup and League Cup going into the final stages of the 1964–65 season, winning the League Cup but faltering late on in the other two. In three seasons the side were beaten in three major semi-finals and were FA Cup runners-up. Under Docherty's successor, Dave Sexton, Chelsea won the FA Cup in 1970, beating Leeds United 2–1 in a final replay. The following year, Chelsea took their first European honour, a UEFA Cup Winners' Cup triumph, with another replayed win, this time over Real Madrid in Athens. Redevelopment and financial crisis (1983–2003) The late 1970s through to the '80s was a turbulent period for Chelsea. An ambitious redevelopment of Stamford Bridge threatened the financial stability of the club, star players were sold and the team were relegated. Further problems were caused by a notorious hooligan element among the support, which was to plague the club throughout the decade. In 1982, at the nadir of their fortunes, Chelsea were acquired by Ken Bates from Mears' great-nephew Brian Mears, for the nominal sum of £1. Bates bought a controlling stake in the club and floated Chelsea on the AIM stock exchange in March 1996 although by now the Stamford Bridge freehold had been sold to property developers, meaning the club faced losing their home. On the pitch, the team had fared little better, coming close to relegation to the Third Division for the first time, but in 1983 manager John Neal put together an impressive new team for minimal outlay. Chelsea won the Second Division title in 1983–84 and established themselves in the top division with two top-six finishes, before being relegated again in 1988. The club bounced back immediately by winning the Second Division championship in 1988–89. After a long-running legal battle, Bates reunited the stadium freehold with the club in 1992 by doing a deal with the banks of the property developers, who had been bankrupted by a market crash. In the mid-1990s Chelsea fan and businessman Matthew Harding became a director and loaned the club £26 million to build the new North Stand and invest in new players. Chelsea's form in the new Premier League was unconvincing, although they did reach the 1994 FA Cup final. The appointment of Ruud Gullit as player-manager in 1996 began an upturn in the team's fortunes. He added several top international players to the side and led the club to their first major honour since 1971, the FA Cup. Gullit was replaced by Gianluca Vialli, whose reign saw Chelsea win the League Cup, the UEFA Cup Winners' Cup and the UEFA Super Cup in 1998, and the FA Cup in 2000. They mounted a strong title challenge in 1998–99, finishing four points behind champions Manchester United, and made their first appearance in the UEFA Champions League. Vialli was sacked in favour of Claudio Ranieri, who guided Chelsea to the 2002 FA Cup final and Champions League qualification in 2002–03. Abramovich ownership (2003–2022) during a 4–0 victory over Portsmouth, August 2008 With the club facing an apparent financial crisis, Bates unexpectedly sold Chelsea F.C. in June 2003 for £60 million. In so doing, he reportedly recognised a personal profit of £17 million on the club he had bought for £1 in 1982 (his stake had been diluted to just below 30% over the years). The club's new owner was Russian oligarch and billionaire Roman Abramovich, who took on responsibility for the club's £80 million of debt, quickly paying some of it. Sergei Pugachev alleged Chelsea was bought on Putin's orders, an allegation Abramovich has denied. Bates mentioned that Abramovich was in talks to buy Manchester United and Tottenham Hotspur before he bought Chelsea in a deal sealed in a day. against Bayern Munich (2012). Over £100 million was spent on new players, but Ranieri was unable to deliver any trophies, and was replaced by José Mourinho. Under Mourinho, Chelsea became the fifth English team to win back-to-back league championships since the Second World War (2004–05 and 2005–06), in addition to winning an FA Cup (2007) and two League Cups (2005 and 2007). After a poor start to the 2007–08 season, Mourinho was replaced by Avram Grant, who led the club to their first UEFA Champions League final, which they lost on penalties to Manchester United. The club did not turn a profit in the first nine years of Abramovich's ownership, and made record losses of £140m in June 2005. In 2009, under caretaker manager Guus Hiddink, Chelsea won another FA Cup. In 2009–10, his successor Carlo Ancelotti led them to their first Premier League and FA Cup Double, becoming the first English top-flight club to score 100 league goals in a season since 1963. In 2012, Roberto Di Matteo led Chelsea to their seventh FA Cup, and their first UEFA Champions League title, beating Bayern Munich 4–3 on penalties, the first London club to win the trophy. The following year the club won the UEFA Europa League, making them the first club to hold two major European titles simultaneously and one of five clubs to have won the three main UEFA trophies. Mourinho returned as manager in 2013 and led Chelsea to League Cup success in March 2015, and the Premier League title two months later. Mourinho was sacked after four months of the following season after a poor start. In November 2012, Chelsea announced a profit of £1.4 million for the year ending 30 June 2012, the first time the club had made a profit under Abramovich's ownership. This was followed by a loss in 2013 and then their highest ever profit of £18.4 million for the year to June 2014. In 2018 Chelsea announced a record after-tax profit of £62 million. In 2017, under new coach Antonio Conte, Chelsea won their sixth English title and the following season won their eighth FA Cup. In 2018 Conte was sacked after a fifth-place finish and replaced with Maurizio Sarri, under whom Chelsea reached the League Cup final, which they lost on penalties to Manchester City and won the Europa League for a second time, beating Arsenal 4–1 in the final. Sarri then left the club to become manager of Juventus and was replaced by former Chelsea player Frank Lampard. In Lampard's first season, he guided Chelsea to fourth place in the Premier League and reached the FA Cup final, losing 2–1 to Arsenal. Lampard was dismissed in January 2021 and replaced with Thomas Tuchel. title (2021) after beating Brazilian side Palmeiras in the final Under Tuchel, Chelsea reached the FA Cup final, losing 1–0 to Leicester City, and won their second UEFA Champions League title with a 1–0 win over Manchester City in Porto. The club subsequently won the 2021 UEFA Super Cup for the second time by defeating Villarreal 6–5 in a penalty shootout, after it had ended 1–1 in Belfast after extra time, and the 2021 FIFA Club World Cup (the first for the club) in Abu Dhabi after beating Brazilian Palmeiras 2–1. On 18 April 2021, Chelsea announced it would be joining a new European Super League, a league competition comprising the biggest European clubs. After a backlash from supporters, the club announced their withdrawal days later. The club opted against furloughing their non-matchday staff during the COVID-19 pandemic, with the decision reportedly coming from Abramovich himself. Chelsea, one of the first clubs to help the National Health Service, lent the club-owned Millennium Hotel for the NHS staff. Amidst financial sanctions leveled at Russian oligarchs by Western governments in response to the 2022 Russian invasion of Ukraine, Abramovich stated on 26 February that he would hand over the stewardship of Chelsea to the trustees of the Chelsea Foundation. The trustees did not immediately agree, due to legal concerns regarding the rules of the Charity Commission for England and Wales. A week later, Abramovich wrote-off the £1.5 billion the club owed him, and put the club up for sale, pledging to donate net proceeds from it to the victims of the war in Ukraine. On 10 March 2022, the British government announced sanctions on Abramovich with Chelsea allowed to operate under a special license until 31 May. In the following weeks, reports emerged of Abramovich's involvement in brokering a peace deal between Ukraine and Russia and securing safe evacuation corridors in besieged Ukrainian cities. An American government official revealed that the Ukrainian president, Volodymyr Zelenskyy had requested that the US government not levy sanctions against Abramovich given his importance to war relief efforts. BlueCo ownership (2022–present) title (2025) under the expanded format after beating French side Paris Saint-Germain in the final On 7 May 2022, Chelsea confirmed that terms had been agreed for a new ownership group, led by Todd Boehly, Clearlake Capital, Mark Walter and Hansjörg Wyss, to acquire the club. The group was later known as BlueCo. The UK government approved the £4.25bn takeover, ending Abramovich's 19-year ownership of the club. Bruce Buck, who served as chairman since 2003, was replaced by Boehly, while long-serving club director and de facto sporting director Marina Granovskaia left, as did Petr Čech from the role of technical and performance advisor. The club brought in Graham Potter from Brighton & Hove Albion to replace Tuchel on 8 September 2022. Chelsea won six of the first 11 games of the 2022–23 season, but only five of the remaining 27. Potter was sacked on 2 April 2023 and eventually replaced by Frank Lampard as caretaker manager. Under Lampard the club won only one of their last 11 matches resulting in a 9% win percentage. Lampard's win percentage was the worst for any Chelsea manager who managed three games or more. Chelsea scored a record-low 38 goals across the entire season and finished in the bottom half of the table for the first time since 1995–96. Mauricio Pochettino was announced as Lampard's replacement in 2023. He led Chelsea to a 6th-place finish, and a place in the Conference League play-off round qualification. He also led Chelsea to the 2024 EFL Cup final, narrowly losing 1–0 to Liverpool. After clashing with the sporting directors Laurence Stewart and Paul Winstanley over strategy and management of the young squad, Pochettino agreed to leave the club at the end of the season. On 3 June 2024, Enzo Maresca was announced as Pochettino's replacement. He led Chelsea to win the Conference League after a 4–1 win against Real Betis in the final in Wrocław, as they became the first team to win all of the European trophies except the European Champion Clubs' Cup, the predecessor of the UEFA Champions League. On 13 July 2025, he also guided Chelsea to victory in the 2025 FIFA Club World Cup, the first edition of the expanded competition, when Chelsea secured the trophy with a 3–0 win over Champions League winners Paris Saint-Germain in the final. He left Chelsea on 1 January 2026 by mutual consent. On 6 January 2026, Liam Rosenior was appointed as the new Chelsea head coach on a six-and-a-half-year deal. He was sacked on 22 April 2026 after losing five consecutive league games, and Calum McFarlane was brought on as interim Head Coach until the end of the season. League history ==Stadium==

, West Stand Chelsea have only had one home ground, Stamford Bridge, where they have played since the team's foundation. The stadium was officially opened on 28 April 1877 and for the next 28 years it was used by the London Athletic Club as an arena for athletics meetings. In 1904, the ground was acquired by businessman Gus Mears and his brother Joseph, who had purchased nearby land (formerly a large market garden) with the aim of staging football matches on the now 12.5 acre (51,000 m2) site. Most football clubs were founded first, and then sought grounds in which to play, but Chelsea were founded for Stamford Bridge. Starting with an open bowl-like design and one grandstand with seating, Stamford Bridge had an original capacity of around 100,000, making it the second biggest stadium in England after Crystal Palace. In 1939, another small seated stand was added, the North Stand, which remained until its demolition in 1975. at Stamford Bridge on 23 September 1905; Chelsea won 1–0. When Stamford Bridge was redeveloped in the Bates era many additional features were added to the complex including two Millennium & Copthorne hotels, apartments, bars, restaurants, the Chelsea Megastore, and an interactive visitor attraction called Chelsea World of Sport. The intention was that these facilities would provide extra revenue to support the football side of the business, but they were less successful than hoped and before the Abramovich takeover in 2003 the debt taken on to finance them was a major burden on the club. Soon after the takeover a decision was taken to drop the "Chelsea Village" brand and refocus on Chelsea as a football club. However, the stadium is sometimes still referred to as part of "Chelsea Village" or "The Village". The Stamford Bridge freehold, the pitch, the turnstiles and Chelsea's naming rights are now owned by Chelsea Pitch Owners, a non-profit organisation in which fans are the shareholders. The CPO was created to ensure the stadium could never again be sold to developers. As a condition for using the Chelsea FC name, the club has to play its first team matches at Stamford Bridge, which means that if the club moves to a new stadium, they may have to change their name. Chelsea's training ground is located in Cobham, Surrey. Chelsea moved to Cobham in 2004. Their previous training ground in Harlington was taken over by QPR in 2005. The new training facilities in Cobham were completed in 2007. Stamford Bridge hosted the FA Cup final from 1920 to 1922, has held 10 FA Cup Semi-finals (most recently in 1978), ten FA Charity Shield matches (the last in 1970), and three England international matches, the last in 1932; it was the venue for an unofficial Victory International in 1946. The 2013 UEFA Women's Champions League final was played at Stamford Bridge as well. The stadium has been used for a variety of other sports. In October 1905 it hosted a rugby union match between the All Blacks and Middlesex, and in 1914 hosted a baseball match between the touring New York Giants and the Chicago White Sox. It was the venue for a boxing match between world flyweight champion Jimmy Wilde and Joe Conn in 1918. The running track was used for dirt track racing between 1928 and 1932, greyhound racing from 1933 to 1968, and Midget car racing in 1948. In 1980, Stamford Bridge hosted the first international floodlit cricket match in the UK, between Essex and the West Indies. It was the home stadium of the London Monarchs American football team for the 1997 season. The previous owner Abramovich and the club's then executive board determined that a larger stadium is necessary in order for Chelsea to stay competitive with rival clubs who have significantly larger stadia, such as Arsenal and Manchester United. Owing to its location next to a main road and two railway lines, fans can only enter Stamford Bridge via the Fulham Road, which places constraints on expansion due to health and safety regulations. The club have consistently affirmed their desire to keep Chelsea at their current home, but have nonetheless been linked with a move to various nearby sites, including the Earls Court Exhibition Centre, Battersea Power Station and the Chelsea Barracks. In October 2011, a proposal from the club to buy back the freehold to the land on which Stamford Bridge sits was voted down by Chelsea Pitch Owners shareholders. In May 2012, the club made a formal bid to purchase Battersea Power Station, with a view to developing the site into a new stadium, but lost out to a Malaysian consortium. The club subsequently announced plans to redevelop Stamford Bridge into a 60,000-seater stadium, and in January 2017 these plans were approved by Hammersmith and Fulham council. However, on 31 May 2018, the club released a statement saying that the new stadium project had been put on hold indefinitely, citing "the current unfavourable investment climate". In July 2022, it was reported that the club's new owner Todd Boehly had appointed American architect Janet Marie Smith to oversee the renovation of the stadium. ==Identity==

Crest Chelsea has had four main crests, which all underwent minor variations. The first, adopted when the club was founded, was the image of a Chelsea Pensioner, the army veterans who reside at the nearby Royal Hospital Chelsea. This contributed to the club's original "pensioner" nickname, and remained for the next half-century, though it never appeared on the shirts. When Ted Drake became Chelsea manager in 1952, he began to modernise the club. Believing the Chelsea pensioner crest to be old-fashioned, he insisted that it be replaced. A stop-gap badge which comprised the initials C.F.C. was adopted for a year. In 1953, the club crest was changed to an upright blue lion looking backwards and holding a staff. It was based on elements in the coat of arms of the Metropolitan Borough of Chelsea with the "lion rampant regardant" taken from the arms of then club president Viscount Chelsea and the staff from the Abbots of Westminster, former Lords of the Manor of Chelsea. It featured three red roses, to represent England, and two footballs. In 1986, with Ken Bates owner of the club, Chelsea's crest was changed again as part of another attempt to modernise and because the old rampant lion badge could not be trademarked. The new badge featured a more naturalistic non-heraldic lion, in white and not blue, standing over the C.F.C. initials. This lasted for the next 19 years, with some modifications such as the use of different colours, including red from 1987 to 1995, and yellow from 1995 until 1999, before the white returned. With the new ownership of Roman Abramovich, and the club's centenary approaching, combined with demands from fans for the popular 1950s badge to be restored, it was decided that the crest should be changed again in 2005. The new crest was officially adopted for the start of the 2005–06 season and marked a return to the older design, used from 1953 to 1986, featuring a blue heraldic lion holding a staff. For the centenary season this was accompanied by the words '100 Years' and 'Centenary 2005–2006' on the top and bottom of the crest respectively. Colours Chelsea have always worn blue shirts, although they originally used the paler eton blue, which was taken from the racing colours of then club president, Earl Cadogan, and was worn with white shorts and dark blue or black socks. The light blue shirts were replaced by a royal blue version in around 1912. In the 1960s Chelsea manager Tommy Docherty changed the kit again, switching to blue shorts (which have remained ever since) and white socks, believing it made the club's colours more modern and distinctive, since no other major side used that combination; this kit was first worn during the 1964–65 season. Since then Chelsea have always worn white socks with their home kit apart from a short spell from 1985 to 1992, when blue socks were reintroduced. Chelsea's away colours are usually all yellow or all white with blue trim. More recently, the club have had a number of black or dark blue away kits which alternate every year. As with most teams, they have had some more unusual ones. At Docherty's behest, in the 1966 FA Cup semi-final they wore blue and black stripes, based on Inter Milan's kit. In the mid-1970s, the away strip was a red, white and green kit inspired by the Hungarian national side of the 1950s. Other away kits include an all jade strip worn from 1986 to 1989, red and white diamonds from 1990 to 1992, graphite and tangerine from 1994 to 1996, and luminous yellow from 2007 to 2008. Songs and fan chants The song "Blue is the Colour" was released as a single in the build-up to the 1972 League Cup final, with all members of Chelsea's first team squad singing; it reached number five in the UK Singles Chart. The song has since been adopted by a number of other sports teams around the world, including the Vancouver Whitecaps (as "White is the Colour") and the Saskatchewan Roughriders (as "Green is the Colour"). Chelsea released the song "No One Can Stop Us Now" in 1994 for reaching the 1994 FA Cup final. It reached number 23 in the UK Singles Chart. In the build-up to the 1997 FA Cup final, the song "Blue Day", performed by Suggs and members of the Chelsea squad, reached number 22 in the UK chart. In 2000, Chelsea released the song "Blue Tomorrow". It reached number 22 in the UK Singles Chart. "Ten Men Went to Mow", "We All Follow the Chelsea" (to the tune of "Land of Hope and Glory"), "Zigga Zagga", and the celebratory "Celery". The latter is often accompanied by fans throwing celery at each other, although the vegetable was banned inside Stamford Bridge after an incident involving midfielder Cesc Fàbregas at the 2007 League Cup final. Popular fan chants include, "Super Chelsea", "Super Frank" (dedicated to all-time leading goal scorer Frank Lampard), "We love you Chelsea" and "Come on Chelsea". There are situation-specific or team-specific chants meant to rile up opposition teams, managers or players. ==Support==

, on 11 March 2006 Chelsea is among the most widely supported football clubs in the world. It has the sixth-highest average attendance in the history of English football, and regularly attract over 40,000 fans to Stamford Bridge; they were the ninth best-supported Premier League team in the 2023–24 season, with an average gate of 39,700. Chelsea's traditional fanbase comes from all over the Greater London area, including working-class parts such as Hammersmith and Battersea, wealthier areas like Chelsea and Kensington, and from the home counties. There are numerous official supporters clubs in the United Kingdom and all over the world. Between 2007 and 2012, Chelsea were ranked fourth worldwide in annual replica kit sales, with an average of 910,000. , Chelsea has 118.9 million followers on social media, the fourth highest among football clubs. During the 1970s and 1980s, Chelsea supporters were associated with football hooliganism. The club's "football firm", originally known as the Chelsea Shed Boys, and subsequently as the Chelsea Headhunters, were nationally notorious for football violence, alongside hooligan firms from other clubs such as West Ham United's Inter City Firm and Millwall's Bushwackers, before, during and after matches. The increase of hooligan incidents in the 1980s led chairman Ken Bates to propose erecting an electric fence to deter them from invading the pitch, a proposal that the Greater London Council rejected. Since the 1990s, there has been a marked decline in crowd trouble at matches, as a result of stricter policing, CCTV in grounds and the advent of all-seater stadia. In 2007, the club launched the Back to the Shed campaign to improve the atmosphere at home matches, with notable success. According to Home Office statistics, 126 Chelsea fans were arrested for football-related offences during the 2009–10 season, the third highest in the division, and 27 banning orders were issued, the fifth-highest in the division. Rivalries Chelsea have long-standing rivalries with North London clubs Arsenal and Tottenham Hotspur. A strong rivalry with Leeds United dates back to several heated and controversial matches in the 1960s and 1970s, particularly the 1970 FA Cup final. More recently a rivalry with Liverpool has grown following repeated clashes in cup competitions. Fellow West London clubs Brentford, Fulham and Queens Park Rangers (QPR) are considered rivals, but less so in recent times as matches have only taken place intermittently due to the teams often being in separate divisions. A 2004 survey by Planetfootball.com found that Chelsea fans consider their main rivalries to be with (in descending order): Arsenal, Tottenham Hotspur and Manchester United. In the same survey, fans of Arsenal, Fulham, Leeds United, QPR, Tottenham, and West Ham United named Chelsea as one of their three main rivals. A 2012 survey, conducted among 1,200 supporters of the top four league divisions across the country, found that many clubs' main rivals had changed since 2003 and reported that Chelsea fans consider Tottenham to be their main rivals, above Arsenal and Manchester United. Additionally, fans of Arsenal, Brentford, Fulham, Liverpool, Manchester United, QPR, Tottenham and West Ham identified Chelsea as one of their top three rivals. ==Records and statistics==

is Chelsea's all-time highest goalscorer. Chelsea's highest appearance-maker is ex-captain Ron Harris, who played in 795 competitive games for the club between 1961 and 1980. Five other players made more than 500 appearances for the club: Peter Bonetti (729; 1959–79), John Terry (717; 1998–2017), Frank Lampard (648; 2001–2014), John Hollins (592; 1963–1975 and 1983–1984), and César Azpilicueta (508; 2012–2023). With 103 caps (101 while at the club) for England, Lampard is Chelsea's most capped international player. Every starting player in Chelsea's 57 games of the 2013–14 season was a full international – a new club record. Lampard is Chelsea's all-time top goalscorer, having scored 211 goals in 648 games (2001–2014); Eight other players have scored over 100 goals for Chelsea: George Hilsdon (1906–1912), George Mills (1929–1939), Roy Bentley (1948–1956), Jimmy Greaves (1957–1961), Peter Osgood (1964–1974 and 1978–1979), Kerry Dixon (1983–1992), Didier Drogba (2004–2012 and 2014–2015), and Eden Hazard (2012–2019). Greaves holds the club record for the most goals scored in one season (43 in 1960–61). While a Chelsea player, Greaves became the youngest ever player to score 100 goals in the English top-flight, at 20 years and 290 days. Chelsea's biggest winning scoreline in a competitive match is 13–0, achieved against Jeunesse Hautcharage in the Cup Winners' Cup in 1971. The club's biggest top-flight win was an 8–0 victory against Wigan Athletic in 2010, which was matched in 2012 against Aston Villa. Chelsea's biggest loss was an 8–1 reverse against Wolverhampton Wanderers in 1953. The club's 21–0 aggregate victory over Jeunesse Hautcharage in the UEFA Cup Winners' Cup in 1971 is a record in European competition. Officially, Chelsea's highest home attendance is 82,905 for a First Division match against Arsenal on 12 October 1935. However, an estimated crowd of over 100,000 attended a friendly match against Soviet team Dynamo Moscow on 13 November 1945. for £50 million; the record stood until 2014 From 20 March 2004 to 26 October 2008, Chelsea went a record 86 consecutive league matches at home without defeat, beating the previous record of 63 matches unbeaten set by Liverpool between 1978 and 1980. Chelsea hold the English record for the fewest goals conceded during a league season (15), the highest number of clean sheets overall in a Premier League season (25) (both set during the 2004–05 season), and the most consecutive clean sheets from the start of a league season (6, set during the 2005–06 season). Chelsea is the only Premier League side to have won its opening nine league games of the season, doing so in 2005–06. From 2009 to 2013, Chelsea were unbeaten in a record 29 consecutive FA Cup matches (excluding penalty shoot-outs). Firsts On 25 August 1928, Chelsea, along with Arsenal, became the first club to play with shirt numbers, in their match against Swansea Town. They were the first English side to travel by aeroplane to a domestic away match, when they visited Newcastle United on 19 April 1957, and the first First Division side to play a match on a Sunday, when they faced Stoke City on 27 January 1974. On 26 December 1999, Chelsea became the first British side to field an entirely foreign starting line-up (no British or Irish players) in a Premier League match against Southampton. In May 2007, Chelsea were the first team to win the FA Cup at the new Wembley Stadium, having been the last to win it at the old Wembley. They were the first English club to be ranked No. 1 under UEFA's five-year coefficient system in the 21st century. They were the first Premier League team, and the first team in the English top flight since 1962–63, to score at least 100 goals in a single season, reaching the milestone during the 2009–10 season. Upon winning the 2012–13 UEFA Europa League, Chelsea became the first English club to win then-all three UEFA club trophies and the only club to hold the Champions League and the Europa League at the same time.

, chairman and one of the co-owners of Chelsea since 2022 Early years Chelsea Football Club was founded by Gus Mears in 1905. After his death in 1912, his descendants continued to own the club until 1982, when Ken Bates bought the club from Mears' great-nephew Brian Mears for £1. Bates bought a controlling stake in the club and floated Chelsea on the AIM stock exchange in March 1996. At the time of the Abramovich takeover, the club had debts of around £100 million, which included a 10-year £75 million Eurobond taken out in 1997 by the Bates regime to buy the freehold of Stamford Bridge and finance the redevelopment of the stadium. The 9% interest on the loan cost the club around £7 million a year and according to Bruce Buck, Chelsea were struggling to pay an instalment due in July 2003. Abramovich paid off some of that debt immediately, but the outstanding £36 million on the Eurobond was not fully repaid until 2008. Since then, the club had no external debt. Abramovich changed the ownership name to Chelsea FC plc, whose ultimate parent company was Fordstam Limited, which was controlled by him. Chelsea were additionally funded by Abramovich via interest free soft loans channelled through his holding company Fordstam Limited. The loans stood at £709 million in December 2009, when they were all converted to equity by Abramovich, leaving the club themselves debt free, although the debt remained with Fordstam. Chelsea did not turn a profit in the first nine years of Abramovich's ownership, and made record losses of £140m in June 2005.

In 1930, Chelsea featured in one of the earliest football films, The Great Game. One-time Chelsea centre forward, Jack Cock, who by then was playing for Millwall, was the star of the film and several scenes were shot at Stamford Bridge, including on the pitch, the boardroom, and the dressing rooms. It included guest appearances by then-Chelsea players Andrew Wilson, George Mills, and Sam Millington. Owing to the notoriety of the Chelsea Headhunters, a football firm associated with the club, Chelsea have featured in films about football hooliganism, including 2004's The Football Factory. Chelsea appeared in the Hindi film Jhoom Barabar Jhoom. In April 2011, Montenegrin comedy series Nijesmo mi od juče made an episode in which Chelsea played against FK Sutjeska Nikšić for qualification of the UEFA Champions League. Up until the 1950s, the club had a long-running association with the music halls; their underachievement often provided material for comedians such as George Robey. It culminated in comedian Norman Long's release of a comic song in 1933, ironically titled "On the Day That Chelsea Went and Won the Cup", the lyrics of which describe a series of bizarre and improbable occurrences on the hypothetical day when Chelsea finally won a trophy. Scenes in a 1980 episode of Minder were filmed during a real match at Stamford Bridge between Chelsea and Preston North End with Terry McCann (Dennis Waterman) standing on the terraces. ==Players==
