The Ox could start against FA Cup opponents Coventry City this weekend.
Wenger said: "He is in advance of where every player of his age is. He is in the national team, a regular player here and he has just been handicapped by a four-month injury but overall he is in a very strong position.
"He can play central and that is not some way off. It is always just finding the right balance because around him you also need a more defensive player. But I like his qualities in the middle because he can penetrate and has good power to get out of pressure, that is a very important quality in the middle of the park.
"He can pass people, can accelerate the game, has a good final ball and a good long pass."
