Manchester City striker Carlos Tevez has cast doubt on his future.
Tevez admits he doesn't know if he will make Brazil's 2014 World Cup.
"The truth is that I do not know whether I will play in 2014," says the 26-year-old striker. "I had to prepare for the tournament in South Africa, but I do not know if I can do that for the championship in Brazil.
"I'm not sure if I still have more to offer the national team.
"The body may indeed be too tired by then."
