"If we don't qualify for Euro 2008, it's over," the 35-year-old Barcelona [ Images ] defender, who has played 134 internationals, said.

France lead Group B and need only a draw in Ukraine next week to advance. They could travel to Kiev already qualified if Italy [ Images ] beat Scotland in Glasgow on Saturday.

"The Ukraine match could mark the end of my adventure," said Thuram.

"There has to be one last match. A final of Euro 2008 which we would win would obviously be a better ending."

The Guadeloupe-born Thuram lifted the 1998 World Cup with France and was a member of their Euro 2000-winning team.
