LONDON (AP) -- Tottenham defender William Gallas has signed a two-year contract extension that ties him to the club until 2013.

The 33-year-old Frenchman joined Spurs on a one-year deal in the offseason on a free transfer from Arsenal. He has played 28 matches for Harry Redknapp's side this season.

Spurs announced the extension on Monday, saying in a statement that "the experienced France defender has impressed at the heart of our defense since joining the club.''

Gallas, who has also played for Chelsea, has captained Spurs at times in the Premier League and Champions League.
