France's most-capped player Lilian Thuram will end his international career if his country fails to qualify for Euro 2008, he told French daily Le Parisien.
"If we don't qualify for Euro 2008, it's over," the 35-year-old Barcelona 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 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."
