Early career Mikel started his football career at the age of 12, when picked as a talented footballer from over 3,000 young talents to play in
Pepsi Football Academy, a team that at the time was well known for travelling across Nigeria scouting young footballers with the potential to play professionally. Obi stood out to scouts and was later picked to play for top-flight club
Plateau United, a side that had previously developed stars such as
Celestine Babayaro,
Victor Obinna and
Chris Obodo, among others, that went on to success in European Leagues. Later known as John Obi Mikel, he made headlines for his country at the
FIFA Under-17 World Championships held in
Finland. Following the tournament, he went on to a trial at South Africa club
Ajax Cape Town, ultimately joining
Oslo-based club
Lyn Fotball in Norway.
Transfer to England On 29 April 2005, a few days after Mikel turned 18,
Premier League club
Manchester United announced that they had struck a deal with Lyn to sign him. United's website also claimed that they had done a deal directly with the teenager and that he had signed a contract to join them. Mikel's agents were bypassed as the club persuaded him to sign a four-year contract without representation. Lyn allegedly sent a fax to his agents abroad, claiming their services were no longer required by Mikel. Reports said the deal was initially worth £4 million, and would see Mikel arrive at
Old Trafford in January 2006.
Chelsea, Manchester United's Premier League rival, later issued a counter-claim suggesting that they already had an agreement with Mikel and his agents, but Lyn denied this claim. Subsequent reports indicated that Chelsea claimed to have been involved in arranging the player's original move to Europe with a view to signing him at a later date. Further substance was added to this claim after it was revealed that the player had impressed Chelsea manager
José Mourinho while training with the club's first-team squad during the summer of 2004. Mikel expressed his delight at joining Manchester United in a hastily arranged press conference, where he was pictured holding up a United shirt bearing the squad number 21. Following his signing of the contract to join United, there were claims from Norway that he had received threatening phone calls from unknown sources. Mikel was assigned a security guard and moved to a safe hotel. On 11 May 2005 he went missing during a
Norwegian Cup game against Klemetsrud; he had not been selected for the match but had been watching from the stands. Whilst he was believed to have left with one of his agents, John Shittu, who had by now flown in to meet Mikel, his disappearance sparked massive media coverage in Norway and also provoked a police enquiry after Lyn director
Morgan Andersen made claims in the Norwegian media that Mikel had been "
kidnapped". These claims were later repeated by Manchester United's assistant manager
Carlos Queiroz, who accused Chelsea of being involved in the alleged "kidnapping". It subsequently emerged that Mikel had travelled to
London with Shittu, who was working for
Jerome Anderson's SEM group. Manchester United manager
Alex Ferguson considered travelling to Oslo to visit Mikel, but decided against this after Mikel was reported to have left the country. Staying in a London hotel and some nine days after disappearing, Mikel stated on
Sky Sports News that he had been pressured into signing the contract with United without his agent present, claims rebuffed by both Manchester United and Lyn. Mikel told the British media that Chelsea were the club he genuinely wanted to sign for. In response to these events, United made a complaint to
FIFA about the behaviour of both Chelsea and the player's agents, Shittu and
Rune Hauge, already infamous for his role in the
George Graham bungs scandal. FIFA dismissed these claims in August 2005, stating there was insufficient evidence to bring a case against Chelsea. Following the tournament, Mikel failed to return to Lyn, and the club subsequently lodged a complaint with FIFA. On 12 August, FIFA ruled that Mikel should return to Lyn to fulfil the remainder of his contract with the club, whilst they would decide at a later date whether the contract he signed with United should be upheld or cancelled. After a delay of over a month, Mikel complied with the FIFA decision and returned to Lyn in early September 2005 after a three-month absence.
Transfer resolved Rather than leaving FIFA to determine the validity of the contract signed with Manchester United, Chelsea intervened by volunteering to settle the transfer saga through negotiation with Lyn and Manchester United. On 2 June 2006, the three clubs reached a settlement. Mikel's registration was to be transferred from Lyn to Chelsea, and Manchester United agreed to terminate their option agreement with him. Under the terms of the agreement, Chelsea agreed to pay United £12 million, half paid upon the finalisation of the contract and the other half in June 2007, and Lyn £4 million, half payable immediately and half in June 2007. As a result of this settlement, all claims in the matter were withdrawn. On 19 July, Chelsea were granted a work permit for Mikel after they completed the £16 million signing in June 2006. In the aftermath of the transfer, Lyn director Morgan Andersen, who had a previous conviction for forging official documents, was convicted of fraud and making false accusations; he was given a one-year suspended jail sentence by an Oslo court. The court also ordered him to pay 20,000
kroner (£1,944) in costs. Chelsea made a High Court claim for £16 million against Lyn and Andersen following the conviction, claiming that the previously agreed settlement was not binding as "the transfer was based on a fraudulent misrepresentation, now proven by a court of law." This claim was subsequently resolved out of court.
Chelsea 2006–07 season On 12 September 2006, Mikel made his first start for Chelsea in the
UEFA Champions League against Bulgarian club
Levski Sofia and took a powerful shot which the
goalkeeper failed to save and
Didier Drogba pounced on the rebound. Mikel received many positive comments for his performance in the match. However, since being sent off in a match against
Reading on 14 October 2006, Mikel was fined on three separate occasions by Chelsea for turning up late to training. At the time, Chelsea manager José Mourinho was believed to have strong reservations about his lifestyle outside of
Stamford Bridge, and the club were reportedly considering offloading the player. Mikel was dropped for over a month, during which his father Michael voiced his concerns over his son's behaviour. After improved punctuality and showings at training sessions, Mikel earned a recall for Chelsea's Champions League group stage away game against
Werder Bremen on 23 November 2006. He scored his first goal for Chelsea in their 6–1
FA Cup victory over
Macclesfield Town on 6 January 2007. He also scored against
Nottingham Forest in the following round of the competition. During Chelsea's triumph in the
League Cup final in 2007, Mikel was sent off in injury time (having come on as a substitute) after clashing with
Kolo Touré. The incident was followed by a huge fracas, in which Touré and
Emmanuel Adebayor of
Arsenal were sent off,
Cesc Fàbregas and
Frank Lampard were booked and Mourinho and
Arsène Wenger were involved in an altercation on the pitch. In subsequent games, Mourinho deployed Mikel as a starter in a holding role in key games where he impressed greatly, notably in the Chelsea–
Tottenham Hotspur FA Cup sixth round replay, the
Champions League quarter-final games against
Valencia, the Champions League semi-final games against
Liverpool and also the victorious
2007 FA Cup Final against Manchester United. Mikel's height and great strength, allied to good ball control and an unusually wide range of passing, allows him not only to disrupt opposing attacks, but also to spread the play effectively. Mikel supplanted the French midfielder
Claude Makélélé in the lineup following his departure to
Paris Saint-Germain.
2007–08 season Mikel was sent-off for the third time in his career in September 2007, when referee
Mike Dean dismissed him for a tackle on Manchester United defender
Patrice Evra. Chelsea appealed against the red card, but the three-match suspension was upheld. Mikel was also sent off in the semi-final of the
League Cup against
Everton for a challenge on
Phil Neville. Despite this, he came back strongly to round off what has been a good first two seasons for him at Chelsea.
2008–09 season The summer of 2008 saw veteran defensive midfielder
Claude Makélélé transferred to French club Paris Saint-Germain, leaving the defensive midfield position vacant. Throughout the
2008–09 season, Mikel saw a great deal of playing time due to an injury to
Michael Essien. During this period of increased action, Mikel performed admirably in the role. His ever-improving game was praised by Chelsea manager
Luiz Felipe Scolari, and his importance to the team was underlined when he provided the free kick that
Salomon Kalou scored to equalise against Manchester United. He played so well in 2008–09 that he was nominated for the club player and young player of the season. On 24 January 2009, Mikel was charged with
drunk driving, just hours before an
FA Cup game against
Ipswich Town – Mikel was not due to play in the game as he was serving a suspension. Although he had all that trouble on 22 July, Mikel signed a new five-year contract with Chelsea.
2009–10 season On 13 February 2010, Mikel provided the assist for
Didier Drogba's goal as Chelsea beat
Cardiff City 4–1 in the fifth round of the
2009–10 FA Cup. Mikel provided another assist for a Drogba goal in a 5–0 win over FA Cup finalists and relegated side
Portsmouth on 24 March, as Chelsea cut United's lead at the top of the table to one point. Mikel played the full ninety minutes in Chelsea's 7–1 smashing of
Aston Villa three days later as Chelsea kept pace in the title race with Manchester United. In their next Premier League game against United, Mikel played excellent as a marshall in midfield as Chelsea climbed above United in the table with a 2–1 win at
Old Trafford, thanks to goals from
Joe Cole and Drogba. Under new manager
Carlo Ancelotti, Mikel continued to perform with efficiency in his defensive midfield role, notching 35 appearances for the Blues. In May 2010, he received
Premier League and
FA Cup winner's medals as part of Chelsea's first ever league-cup double winning team.
2010–11 season Mikel and Chelsea started the new
2010–11 Premier League campaign where they left off from the 2009–10 season, playing strong defense and adding deadly finishing. Mikel played the full 90 and helped keep three clean-sheets in the first three games as Chelsea eased past
West Bromwich Albion 6–0 on 14 August, crushed
Wigan Athletic 6–0 at the
DW Stadium seven days later and edged past
Stoke City 2–0 on 28 August. Mikel was the preferred option in defensive midfield as teammate Michael Essien spent most of the season on the sideline with knee injuries. The injury to the versatile Essien forced the club to play new signing
Ramires more often in the second half of the season. Mikel featured in 28 Premier League campaigns for Chelsea as the London side finished in second place, nine points behind champions Manchester United. Following the disappointment of not winning a title, Chelsea manager Carlo Ancelotti was sacked by the club.
2011–12 season Before the start of their league campaign, Mikel's father was abducted in his native Nigeria on 10 August; despite this, Mikel started in the club's opening fixture against Stoke City at
Britannia Stadium. Mikel came close to claiming his first Premier League goal for Chelsea in an inspired game as the sides played out a 0–0 draw in new coach
André Villas-Boas' first game in charge. Due to Essien's long-term knee injury, Mikel found more playing time, but around Christmas time lost his place to new signing
Oriol Romeu. Following a run of disappointing fixtures, including a catastrophic 3–1 loss to
Napoli in the
Champions League round of 16 first leg and a 1–0 defeat to West Brom, Villas-Boas was sacked by Chelsea owner
Roman Abramovich. In both of these matches, Mikel was an unused substitute for the Blues. Following the appointment of former Chelsea midfielder
Roberto Di Matteo as interim head coach, Mikel appeared in 16 of the club's last 20 games and started in 14 of them, and began to play some of his best football for the club. Mikel played the full 90 minutes in Chelsea's 2–1 victory over
Liverpool in the
2012 FA Cup Final on 5 May 2012, picking up a yellow card in the 36th minute. Chelsea played a tough defensive battle and Mikel was hailed by
Sky Sports pundit
Jamie Redknapp as playing an excellent game, putting in "a performance that I didn't think he had in him; he was putting out fires everywhere," as Chelsea claimed a 4–3 victory in the penalty shootout. Mikel's strong performances in the final stages of the season and his impressive display in Munich helped Chelsea secure
Champions League football next season despite finishing in sixth place, knocking London rivals Tottenham into the
UEFA Europa League.
2012–13 season Mikel started all of Chelsea's first five games of the new
2012–13 Premier League season, and also played in the
Community Shield against
Manchester City and
Super Cup against
Atlético Madrid. In November, Mikel was named on the shortlist for the
African Footballer of the Year along with former Chelsea teammate Didier Drogba. Mikel was charged with misconduct by the
Football Association (FA) on 22 November 2012. He was given a three-match ban and fined £60,000 for threatening referee
Mark Clattenburg during a 3–2 defeat to Manchester United. On 5 December 2012, Mikel signed a contract extension with Chelsea, keeping him at the club until 2017.
2013–14 season On 21 September 2013, Mikel scored his first-ever Premier League goal in a 2–0 win against
Fulham. He scored his second goal of the season in Chelsea's third round tie with
Derby County on 5 January 2014, heading in the opening goal in an eventual 2–0 victory. He made his 200th Premier League appearance for Chelsea on 3 February, coming on as a late substitute in a 1–0 away victory at Manchester City.
2014–15 season On 30 August 2014, Mikel, who substituted
Willian on the 75-minute mark, set up
Diego Costa's second goal after intercepting up
Muhamed Bešić's backheel pass. Chelsea went on to win 6–3 against Everton at
Goodison Park. Mikel scored a rare goal against
Sporting CP on 10 December in a 3–1 victory at Stamford Bridge in the
2014–15 Champions League.
2015–16 season Against
Watford on Boxing Day 2015, in the first game of
Guus Hiddink's second spell in charge, Mikel came on to become the 21st player to make 350 appearances for Chelsea. Chelsea then faced
Paris Saint-Germain in the first leg of the
UEFA Champions League round of 16. Mikel conceded a foul just outside the
18-yard box. PSG forward
Zlatan Ibrahimović's
free kick deflected off Mikel, who was part of
the wall, and past goalkeeper Thibaut Courtois. Just a few minutes later, however, Mikel equalised from a stoppage time corner kick. Due to the injuries of John Terry and Gary Cahill, Mikel had to play as a centre-back in multiple games.
2016–17 season On 4 November 2016, it was announced that the club would not be renewing Mikel's contract when it expired at the end of the season.
Tianjin TEDA On 6 January 2017, Chinese club
Tianjin TEDA signed Mikel on a free transfer. On 14 April 2018, he scored his second league goal for Tianjin, and first goal of the season against
Guangzhou R&F. He left Tianjin TEDA at the end of the 2018 Chinese Super League season in November 2018.
Middlesbrough After two years in China, Mikel joined English
Championship team
Middlesbrough on a short-term deal in the 2019 winter transfer window. The 31-year-old was a free agent after leaving Chinese side
Tianjin TEDA. Mikel made 19 appearances for Boro, scoring once against
Rotherham United on 5 May 2019 as the team narrowly missed out on a play-off spot finishing seventh. He was released by Middlesbrough at the end of the
2018–19 season.
Trabzonspor In the summer of 2019, Mikel joined
Trabzonspor on a two-year contract with the option of a further year. It was announced on 17 March 2020, that Mikel had left Trabzonspor by mutual consent, days after expressing his concerns about the Turkish Super Lig continuing amid the global coronavirus pandemic.
Stoke City Mikel signed a one-year contract with
EFL Championship side
Stoke City on 17 August 2020. He made his Stoke debut on 13 September 2020 in a 0–0 draw away at
Millwall. Under
Michael O'Neill, Mikel was a key member of the team in
2020–21, making 41 appearances as Stoke finished in a mid-table position of 14th. At the end of the season O'Neill stated that he wanted Mikel to stay at Stoke for another year.
Kuwait SC and retirement On 1 July 2021, Mikel cancelled his contract agreement with Stoke and moved to
Kuwait SC. On 4 November 2021, the contract with Kuwait SC was terminated after only four months of joining the team. On 27 September 2022, Mikel announced his retirement from professional football at the age of 35. ==International career==
