Tevez has not played for his country since 2011 after falling out of favour under Argentina coach Alejandro Sabella.
He has been in superb form for Juventus this season but still doubts whether he will be involved in Brazil.
"I don't think my goals can convince Sabella to take me to the World Cup," the 29-year-old told Tuttosport.
Tevez took his Serie A tally to 10 goals in 16 games with a hat-trick in Sunday's 4-0 victory over Sassuolo, as Juve opened up a five-point gap at the top.
"I want to win the Scudetto with Juve, so I would also like to win the Capocannoniere (top scorer) crown," he continued.
"I look to just do my best - sometimes I am able to do that, others I am not.
"The season is not over and we'll look to win every trophy available to us."
