William Gallas (born 17 August 1977) is a defender who played for Chelsea between 2001 and 2006.
Gallas joined Chelsea from Marseille for £6.2 million in May 2001. A quick, intelligent and versatile defender, he was capable of playing anywhere across the back four and made his Chelsea debut in a 1-1 opening day draw with Newcastle United. Gallas was a part of the Chelsea team which reached the FA Cup Final that season, losing out to Arsenal at the Millennium Stadium. In 2004-05 he formed a formidable central defensive partnership with John Terry; at one point, the pairing went 16 matches without conceding a goal as Chelsea romped to the Premier League title.
In the following season Gallas was often deployed as a full-back due to José Mourinho's preference for the pairing of Terry and Ricardo Carvalho, a situation Gallas grew increasingly frustrated with. He nonetheless helped Chelsea to their second consecutive league title, which included goals against Liverpool and Fulham, and a vital last minute winner against Tottenham. He also opened the scoring in Chelsea's title-clinching 3-0 victory over Manchester United.
As the season drew to a close it was apparent that contract negotiations between Gallas and Chelsea had broken down. In pre-season new signing Michael Ballack was assigned Gallas' number 13 shirt and on the final day of the transfer window Gallas was sold to Arsenal in a £5 million part-exchange deal which saw Ashley Cole move in the opposite direction.
