I feel sorry for Moyes in a way, that Man United job has tarnished him.
I felt sorry for him after the United job, where he was clearly brought in with the expectation of failure. Everyone knew that Ferguson neglected the team for the last few years of his tenure and it was all gonna fall apart without him, so they needed a gullible idiot who would parade up and down being dead proud of himself, acting all billy big bollocks, not knowing that it's all a ruse.
But after that he had a genuine chance to become a better manager at Real Sociedad and he chose to be a dick instead, then he was given another chance to restore his reputation with Sunderland and he fucked that up just as badly.
He can only blame himself for how his career has turned out after United.
