Argentina coach Tata Martino is disappointed with Barcelona star Lionel Messi's knee injury.

Messi is out for the next few weeks with a knee problem, but the former Blaugrana manager isn't going to ask Boca Juniors striker Tevez to play like Messi.

"Tevez cannot do Messi's role because Lionel plays like a number seven and I do not see Carlos playing there," Martino explained on beIN Sports.

"For Carlos it does not suit him at all to go to the wings. He can play in the position that he did at Juventus or how he does now at Boca."
