• Joined Lyn at the start of the 2005 season but made only six league appearances before Chelsea and Manchester United FC engaged in a long battle for his services, the Blues coming out on top in 2006 when he signed for the Stamford Bridge club at a cost of €16m.
• Sent off in Chelsea's 2007 League Cup final triumph over Arsenal FC but played the full 120 minutes of the FA Cup showpiece victory against United (1-0) a few months later; became a regular thereafter, particularly after Claude Makelele's departure, starting 33 Premier League games in 2008/09.
• Suffered a knee injury in the closing stages of Chelsea's double-winning 2009/10 campaign which caused him to miss the FA Cup final and the FIFA World Cup in South Africa.
• In May 2012 he appeared in his third successful FA Cup final, a 2-1 victory against Liverpool FC, two weeks before playing the full 120 minutes of Chelsea's UEFA Champions League shoot-out triumph over FC Bayern München.
