Their european record is rubbish for how good they think they are.
Their dominance is down to being the richest club in the world, getting all the refereeing decisions and probably more importantly having the same manager for 25 years.
Any manager will put together some wins in that time, even Rogers (maybe).
Managers are turned over too often these days, Fergie has been there and their consistancy in the club, that is all no big secret. I don't think he is that good of a coach.
I would like to see him go to a different league and see how well he does!
