Just reiterating what many other have said, he does a job in a more defensive format. Personally I reckon he'll be in there on Tuesday night giving a bit more defensive cover across the field allowing Ritchie and Rooney to be more attacking. But I probably dont know what Im talking about.
Rate him more than most people do. Because of the type of job he does he won't ever "create" lots, which people notice (a la Ritchie/Rooney) and you'll also notice his fuck ups a lot more other players.
He's one of those players where when he's doing his job right, you'll think he only had a "good" game, shutting everyone out of mid.
I reckon Paolo will want that type of player for an away game... shut up shop in central mid.
