Whether here or elsewhere, I think he'd be better off being converted into a central midfielder. Defensively he is poor, but his ability to keep the ball under pressure, dribble, produce quick 180 turns at the drop of a shoulder, and his impressive range of passing would all be more beneficial centrally than at full back where his poor defensive play outweighs the benefits he brings on the ball.
That's the most surprising thing I've noticed about him at Norwich. I always knew he could dribble and carry the ball well, and knew of his defensive limitations, but his passing this season has been very impressive.
