Yeah, Smalling's a good player but he still lacks experience and something like that (playing the ball behind him) is something which improves with age etc.
Moses got in behind before though (Although I only caught the finish, not build up..).
O'Shea on the other hand, is far too narrow and is being given the run around whenever Wigan get the ball wide. Better crossing needed, but Utd don't look like they're going to concede any time soon.. Would like to see N'Zogbia take on O'Shea on the inside and get into the area to draw a challenge or have a shot..
That, or switch to the right and try and get behind Evra when he gets forward.
