Arsenal boss Wenger: Cesc can be world's best
"If he is doing what he is doing at 20 why should he not aim for that? It is not done yet though and I think that he knows that too.
"It is remarkable where he is at his age, but talent needs to make an early appearance and with Cesc he played at 16 and a half in the first team at Arsenal and that should tell you that if this player is right mentally then he will go a long way.
"He is right mentally and that is why he is where he is today."
