I really think he can reach Cafu's or Maicon's level in the long run, he has the physic and speed, along with the good basic technique also he does not do those one dimensional plays, he tries to play accordingly to the situation and teammates, one example I can think of is even for the first match he played for Inter, when he received the ball up front he tried to protect it for possession, instead of rushing for the break through which is more often what he did for the national team. This also explains why he appears to be slow on acting, cause he is trying to read his teammates movements, and he is not familiar with them at this point. His current weakness though I would say is his def skills set you can see he gets beaten a lot and seem quite clueless on how to limit the man he is marking, but at least he has the work ethic for it, which he keeps tracking back and trying.
