I'm not sure why anybody would feel sorry for him when he knew what he was getting into before he came, he knew it and he accepted it, now he has to get on with it.
Our team performances are rarely equal to or better than the sum of it's parts, that is down to him and his poor management, not anything that has gone on behind the scenes. Other than that he's a slimy prick who does whatever his boss asks of him because he must have no self respect. Any person in his position who has any self respect would walk if things were bad enough and he doesn't, even though he has a contract to fall back on if he thinks the club is not honouring whatever they promised him. Keegan walked and the club had to honour his contract, they would have to do the same for Pardew if he was being unfairly treated in line with his contract, the fact that he doesn't walk suggests that he's happy with his treatment.
