However, the 33-year-old admits that he is proud of the way he has repeatedly returned to action following injury setbacks.
"But I still feel I've managed to do something amazing and, even with all the injuries, I'm still fighting. I still managed to play 500 games. Which is not bad," Saha added.
The Former Fulham striker has played for Les Bleus on 20 occasions.
