Early career Born in
Paris, He began his professional career with
Red Star 93 before joining
Catanzaro during the 1999–2000 season. He made 34 league appearances and scored nine times for the
Calabrian club before signing for
Modena. In three seasons there, he scored 15 times in 82 appearances, impressing many with his speed and agility.
Portsmouth In August 2004,
Portsmouth wanted to sign Kamara for a loan deal but eventually signed him for £2.5 million for a permanent transfer, making him their then record signing. However, despite a bright start, Kamara struggled for form and injuries during the
2004–05 season, and after just one year at Portsmouth they took advantage of a clause in his contract which allowed them to move him on to
West Bromwich Albion whilst only paying £1 million of his initial transfer fee to Modena. Albion paid £1.5 million for Kamara.
West Bromwich Albion Kamara made his Albion debut on 13 August 2005, replacing
Kanu in the 60th minute in a 0–0 draw away at
Manchester City. He picked up a yellow card in each of his first three games for the club. His first goal for West Brom was scored in a 4–1 Hawthorns win over
Bradford City in the
League Cup, on 20 September 2005. It was one of only two goals scored by Kamara during
2005–06; his first league goal for the club was scored against
Manchester City on 10 December 2005, Albion winning 2–0. Albion were relegated from the Premier League that season, but
2006–07 saw Kamara hit a rich vein of form, netting 23 goals in all competitions and helping Albion reach the playoff final. His goalscoring exploits earned him the
Championship Player-of-the-Month award for October 2006, as well as the
PFA Fans' Player-of-the-Month award for February 2007. He was also named in the
PFA Championship Team of the Year and won the West Bromwich Albion
Player of the Year award.
Fulham . On 9 July 2007, Kamara signed a four-year deal with
Fulham for £6 million and the move was a club record sale from
West Brom. Following his move to Fulham, he vowed that he could score 'a lot of goals' in the Premier League with Fulham. He made his debut for the Cottagers in a 2–1 defeat away at
Arsenal on 12 August 2007, replacing fellow debutant
David Healy in the second half. Kamara scored his first goal for Fulham in a 1–0 win at
Shrewsbury Town in the League Cup, on 28 August 2007. Four days later, he notched his first league goal for the Cottagers, a superb late overhead kick to earn a 3–3 draw with
Tottenham Hotspur. After the match, Kamara told the club's official website that the overhead kick goal was "classed the goal as possibly the best of his career". On 25 November 2007, he scored his second goal, in a match against
Blackburn Rovers which ended in a 2–2 draw. On 29 March 2008, he scored his third goal, against
Derby County in another 2–2 draw, which resulted Derby County being relegated to the Football League. Later in the 2007–08 season, after having a relatively dry spell in front of goal, Kamara resurrected Fulham's Premier League survival hopes with two goals in the last twenty minutes (plus a
Danny Murphy rebound from a
penalty saved by
Joe Hart) secured a rare away win against Manchester City. Fulham eventually survived relegation, in the last game. Whilst playing for
Senegal in a match against
Liberia in June 2008, he ruptured his
cruciate ligament, an injury which required
reconstructive surgery. In his first start for the Cottagers since his injury Kamara scored a brace against
Aston Villa and also made an assist to Danny Murphy to score, helping his side win 3–1 on 9 May 2009. After the brace, manager
Roy Hodgson praised Kamara's good performance. Kamara also scored in the following match, netting the winning goal in a 1–0 over
Newcastle United on 16 May 2009. After the 2008–09 season, Kamara was linked with a move to join French Champion
Bordeaux who wanted him to replace the departing
Marouane Chamakh who joined Arsenal, with Roma keen to sign him as well. However, the move was rejected as Kamara was not interested in a move overseas but instead hoping to find a new club in the UK. In the Premier League 2008–09 and 2009–10 seasons, Kamara began playing less in the Premier League. He scored his only league goal in the 2009–10 season for Fulham in a 2–0 victory over
Hull City on 19 September 2009. On 17 September, he helped Fulham secure an away draw against
CSKA Sofia which ended 1–1 in the
Europa League. On 5 November 2009, Kamara scored from a penalty after being fouled in the penalty box in a match against Italian side
Roma; he was substituted off in the 46th minute for
Erik Nevland and Fulham went on lose with a two-goals comeback from Roma. On 1 December 2009, he suffered knee problem which kept him out for one month. He made his return for Fulham in a 2–0 loss against
Tottenham Hotspur on 26 January 2010 after coming on for
Zoltán Gera in the 72 minute.
Loan to Celtic On 1 February 2010, Kamara moved to
Celtic on loan until the end of the
2009–10 season, and Celtic had an option to make the deal permanent if he impressed during his loan stint. His move to Celtic was allowed after Fulham brought
Stefano Okaka on loan from Roma. Kamara had previously played under then-Celtic manager
Tony Mowbray at
West Bromwich Albion. He made his debut on 2 February 2010 against
Kilmarnock at
Rugby Park in a 1–0 defeat. On 13 February, he scored his second goal for Celtic and his first
SPL goal, against
Aberdeen in a 4–4 draw at
Pittodrie. He also provided the assist for a goal from Keane who had assisted Kamara's goal. On 20 February 2010, Kamara provided an assist for Keane who scored a winning goal against
Dundee United in a 1–0 win. He then suffered an injury that kept him out about one month and made his return on 13 April 2010 against Motherwell in a 2–0 win. On 25 April, he scored the first of two goals in a 2–0 win against Dundee United after returning from injury. As his loan spell was set to expire, Kamara revealed he wanted to stay at Celtic permanently and that he would happily stay on at the club under interim boss
Neil Lennon after the sacking of Tony Mowbray. He revealed that he set his sights on securing a permanent deal at the club and described it as his 'priority' to stay at Celtic. However the move never happened, as Celtic decided not to pay the £2.5 million buyout clause in his contract. Kamara returned to Fulham and set his sights on a move to his boyhood club
PSG.
Return to Fulham Upon his return to Fulham, Kamara stated that the newly appointed manager of Fulham,
Mark Hughes, had made him stay and that he had been given a fresh chance. He also said that he would have left Fulham if Roy Hodgson had stayed in charge of the club (he became manager of Liverpool instead). Kamara did get more playing time for Fulham as the club was short of options following injuries to
Bobby Zamora and
Mousa Dembélé. He scored his first league goal of the 2010–11 season on 16 October 2010 against
Tottenham Hotspur, in a 2–1 defeat in the 30th minute at
Craven Cottage. He also scored in a 2–1 defeat against
Arsenal on 4 December 2010 at the
Emirates Stadium in the 30th minute, playing 73 minutes of the match before being replaced by fellow striker
Andrew Johnson. Despite the loss, manager Mark Hughes praised Kamara's performance, whilst Kamara stated that he was keen to hold down a regular first team place. On 8 January 2011, Kamara netted a hat-trick and played the full 90 minutes in the third round of the FA Cup against
Peterborough United in a 6–2 victory at Craven Cottage. However, after the return of Zamora and Dembélé from injury, further opportunities were limited.
Loan to Leicester City Leicester City signed Kamara on loan until the end of the
2010–11 season on 21 March 2011 after Leicester City manager
Sven-Göran Eriksson confirmed his interest in signing him. Kamara made his competitive debut against
Middlesbrough on 2 April 2011, making an assist in a 3–3 draw. He scored his first goal in a 4–0 win over
Burnley on 9 April. He scored his second goal against
Ipswich making the score 4–2. It was the last league goal to be scored at the
Walkers Stadium before it was renamed to King Power Stadium in summer 2011. After his loan spell finished, Kamara admitted his contribution was disappointing at Leicester City but was open to a return.
Eskişehirspor On 24 June 2011, Fulham announced that Kamara would not be renewing his contract and had left the club to sign with
Süper Lig club
Eskisehirspor. On 10 September 2011, Kamara made his debut in the Eskişehirspor shirt against
Beşiktaş in a 2–1 win. The following week, he scored his first goal for Eskişehirspor in a 4–0 win over
Sivasspor on 18 September 2011. Kamara continued his goalscoring form and became the top scorer for the club in his first season with 10 goals and the second top assist provider with 5 behind defender
Dedê with 10.
NorthEast United On 7 July 2015, he signed for
Indian Super League club
NorthEast United FC. ==International career==
