Oxdale Chamberlain is a good shout, would fit in nicely and possibly get a few goals as well. Personally think that as a key signing we need to make sure we get a striker, either Lukaku or a similar player.
As with United, Arsenal might just have a new manager in the summer, Spurs certainly will. This means the new managers will probably buy in a few players to put their stamp on the squad and some players will then become available. I think one £15m signing for a striker and we can still get a few more quality players cheap.
