Campbell's an arsehole, he wont be coming here to mentor anyone or sit on the bench. He'll also likely cost us the chance of bringing in someone with a future as a result of his massive wage demands.
The one benefit I could see is that it would allow S Taylor to play in his best position at RB, but the Taylor - Coloccini central partnership has looked quite promising and we need to start building with the future in mind. The defence imo is the one part of the team that is fit for the premiership, do we really want to jeopordize that?
