Wenger is seeking more goals from Wilshere.
He said: "Cazorla is 28 and he has never reached double figures in his whole life before. He comes to us and he has 11 goals already.
"That means we play very offensively and that at any age you can develop that skill. I think it is right that Cazorla has been liberated by Jack, who can pass somebody and give you the ball. That is very important."
