Manchester City striker Carlos Tevez says he'll quit the game when he feels his body has had enough.

Tevez admits he may not make Argentina's 2014 World Cup campaign.

He said: "It grinds going through my head. I like to play for the national team, but I do not know if I can hold out until 2014.

"In the future, I do not know if my body can cope with his workload."
