Wenger believes that playing in a more advanced role than he is used to has helped Wilshere's game and is allowing him to rediscover his form after his recent injury problems.
"It does [bring the best out in him]," he told reporters. "It depends always on the collective performance because Jack is an intelligent player who finds little holes on the pitch where he can use his ability to turn the ball forwards.
"What is good for him now is that he also starts to find goals. Then he will be naturally attracted to play in a more advanced position."
