William Gallas has announced his retirement from football.
The French defender, who won 87 caps for his country, had spells at Arsenal, Chelsea and Spurs, before finishing his career in Australia with Perth Glory.
The 37-year-old told L'Equipe: "It is not an easy thing to announce. You always tell yourself that you can keep going, but I think today I cannot go on any longer."
Gallas won two Premier League titles during his time at Stamford Bridge.
