The refs admitted their mistakes in the Man U Celtic game. They were lucky that Man U scored a legal goal, and that one of their three goal mistakes was ruling a good goal offside. Personally, I do not share their confidence in asserting that Manchester would have won anyway. It only opened up because the illegal goals forced Celtic to gamble more. In truth I'm getting really sick of decisions going against Scottish teams just because the opposition are bigger ... it's happening too consistently.
