France defender Lilian Thuram has admitted he may have to retire from international football before Euro 2008.
The 35-year-old has been a stalwart of the France side for the past decade but he has not been a regular for Barcelona this season.
He knows he may be struggling to play at an international standard in 18 months time and is worried about letting his country down.
Thuram is determined not to selfishly cling on to his place and is considering hanging up his boots.
"I must admit I am 35-years-old and the 2008 European Championships are very far away," he told Canal+.
"And furthermore, I don't play much with Barcelona these days
"If it goes on, it will be difficult for me to play the Euro.
"When you don't play much, it is hard to remain at a very high level. There are a lot of youngsters and if they show good things it is normal to say to 'Lilian Thuram: your time has come, we don't count on you anymore'.
"When you are not equal to the situation you have to let your place go. You can't cling to it."
