I really can't believe people are blaming Hibbert for that goal.
The assist shouldn't have been allowed to happen in the first place, and Yobo is caught ball watching yet again, and Howard stands his ground rather than come for the ball sooner thinking Yobo will deal with it, and Hibbert, from his own innocent position sprints his ass off and tries to clear the ball. Sometimes you get lucky, and sometimes you don't, but blaming Hibbert is the equivalent of a kitten falling out of a tree, and a man running to try and catch it, but failing to do so. It's not the man's fault the damn kitten was up the tree. At least he had a go while others watched in horror.
The team give the opposition too much time on the ball, except Fellaini and Heitinga, who get stuck in, and as long as the team do that, we'll always have problems.
