Martinez is joining Inter from Racing Club in Argentina.
“What a player he is," Tevez told Corriere della Sera.
“He's hungry, ruthless and technically gifted. He reminds me of myself a few years ago. Of the young Argentines, he is by far the best and can get even better.
“Inter pulled off a coup by signing him. They'll love him. Argentina at the World Cup? I hoped I'd make it."
