Wiltord was part of Arsenal's 'Invincibles' side of 2003-04, which went won the Premier League that season by going the entire campaign unbeaten.
During his four years in north London after joining from Bordeaux for a then club-record £13 million, Wiltord also the league and cup double in 2001-02 and helped the Gunners retain the FA Cup the following year.
In the international arena, Wiltord scored 26 goals in 92 appearances for Les Bleus, none more memorable than the one he netted in the dying moments of normal time in the Euro 200 final against Italy to level the match at 1-1. David Trezeguet scored a golden goal in extra time which crowned France as European champions to go with the World Cup they won two years earlier.
The French Football Federation said in a statement: "All of our football fans who were following the final of the European Championship on the evening of July 2 in Rotterdam as supporters of France will long remember Sylvain Wiltord's equalising goal in added time before the French won in extra-time.
"This memory will remain etched in the history of our sport, because he made a big contribution to winning the European title."
Wiltord won three Ligue 1 titles with Lyon upon his return to France in 2004. He spent last season at second-division side Nantes.
