Personally if he is to start I think it should only be right back, if he can just improve the defensive side of his game a little (easy said) he would be very good there. I just don't think he has enough in his game to push for a start anywhere else. He could play on the wing but he'd need to be a hug the touch line winger and that doesn't really fit in with the likely formations and he doesn't really take on players, his runs are about space, pace and timing which he utilises quite well at right back.
