I don't think we really NEED anyone, we could mostly do with a bit of cover for important players like Cork, Schneiderlin, Clyne, Boruc, Shaw etc. Those guys are pretty much the only decent guys in their positions with no other replacements who could play at the same level consistently. I feel like the only problem we have with our current squad is the fact that if someone crucial to the team were to suffer a long-term injury we'd be pretty ****ed.
