Wenger believes that Wilshere has the attributes to play anywhere on the pitch, but will benefit from being forced to find a yard of pace out wide in tight situations.
He told the club's official website: "Deep-lying midfielder or wide [are his best positions] because higher up he is less comfortable at the moment. He doesn't like to have his back to goal, he likes to face the game.
"Why? Because he has a burst to pass people with the ball at his feet. He is getting it back and I think playing on the flanks helps him to find that back, because on the flanks you have to do a lot of that.
"You ask every good football player and he says to you [he wants to play] 'in the centre'. Nobody says I want to play wide, I've never heard that."
The 21-year-old also drew criticism from Wenger yesterday after being photographed smoking a cigarette outside a London nightclub in the early hours of Friday morning.
