Tevez has denied he told Argentina coach Alfio Basile not to consider him for the World Cup qualifying match against Brazil on June 18.
The 24-year-old is unable to play against Ecuador four days earlier, as he is suspended, but dismissed speculation he did not want to play through fatigue.
He said: "I want to talk to Basile. They are saying that I withdrew because I was physically tired but people know what I feel for the national shirt.
"If we beat Barcelona, the Champions League final is on May 23. The Brazil match is on June 18, so I will have more than 20 days to recover. It is a derby and everybody knows how we live for these type of matches."
