Michael Ian Mancienne (born 8 January 1988 in Isleworth, London, England) is an English Under-21 international who was at Chelsea until the summer of 2011, having joined the club as a junior. Primarily a centre back, he can also play at full back or as a defensive midfielder.
Michael joined Chelsea at the age of nine after the club spotted him playing for Kingstonian.
He quickly became one of the club's most talented young players and was representing both the Under-18 team and the Reserve side whilst still at school (coincidentally the same school as James Simmonds). A regular at the heart of defence, he signed a professional deal at the age of eighteen and was called into José Mourinho's senior squad towards the end of the 2005-06 season.
Mourinho was clearly enamoured with his talent and took him on tour to the United States before naming him on the substitute's bench for two early-season fixtures in 2006-07. For the majority of the campaign, however, Michael would play his football at the other end of the London Borough of Hammersmith & Fulham, joining Q.P.R. in the Championship.
In 28 appearances he grew into a fan favourite and showed his ability in a new position. Due to concerns about his average height and slight stature, he was moved to right-back, where his natural athleticism and ability on the ball shone through. The Hoops were impressed enough to bring him back for another season in 2007-08, but Chelsea made a statement of intent that summer by tying Mancienne down to a long-term deal.
The loans continued to follow, with no apparent breakthrough to the first team in sight. Another spell in The Championship came at the start of the 2008-09 season at Wolverhampton Wanderers, but an administrative error cut the spell short in January 2009 and he returned to Stamford Bridge.
On 14 February 2009, Mancienne finally made his Chelsea debut, three years after first being called into the first team squad. He continued to play a part in new manager Guus Hiddink's plans, making both a Premier League and Champions League bow in the following fortnight.
Despite impressing, he was once again sent out on loan when Carlo Ancelotti arrived in the summer of 2009, and spent the 2009-10 season back at Wolves, but this time in the top flight. After a shaky start to the season, he was moved out of the back four and into a shielding role in the midfield. He grew accustomed to the role and earned rave reviews, particularly for a sterling performance away to Arsenal in early 2010. He returned to Chelsea at the end of the campaign, but returned to Wolves for the 2010-11 season, and with Chelsea declining to recall the defender in January he remained at the club for the entire season.
On 31 May 2011 it was announced that Mancienne had agreed to sign for German side Hamburg SV, on a 4-year deal for a fee in the region of £1.75 million, with the deal to be completed on 1 July 2011 when the transfer window opened. Mancienne was signed on the recommendation of Sporting Director Frank Arnesen, who had recently joined the German club upon leaving Chelsea, where he had performed the same role. 
Michael has represented England at every junior level from Under-16 to Under-21, where he had 21 caps as of August 2010.
In November 2008, Fabio Capello invivited him into the senior England squad for a friendly against Germany. He was part of the matchday squad, but did not feature.
He also retains Seychellois nationality on his father's side, but rejected the opportunity of a call-up as a teenager.
