It was blatantly obvious that Campbell just needed to get out of Arsenal.
You don't go from a world-class defender to a poor one just like that. He was just finished there, that's all. Not enough games, not enough support, not enough confidence - it had just gone sour. He's gone to Portsmouth to be the uber-leader, and speahead the defense, with an ecstatic welcoming from the supporters.
And guess what. Fucking superb season.
Insane that Roeder turned him down.
