The problem is have in calling out individuals as THE problem at a club is that rarely do they work in isolation. We also have no understanding of the inner workings of the different clubs and the politics involved. Sunderland have been ran terribly for years. Celtic had some well publicised transfer budget problems, and as per the article above the remit at Hambug completely changed.
We've seen this with Rudkin being blamed for every bad signing and not signing players. (At least on the other side)
He may turn out to be shit. In which case I wouldn't necessarily blame just him, but the whole structure of our club and the recuitement process. No one person makes signings now a days. We're not run by a dictator chairman or agents.
