As a Leeds fan I hate to say it but he is one of the best managers ever. If only his attitude wasn't so bad and he didn't call referees 'unfit' simply because he didn't win a match. Seriously the amount of time added on at the end of matches at Old Trafford if Man Utd are losing is sometimes just beyond belief! But the managing part he is second to none. Signing Ronaldo as youngster for around £10M I think (not fully sure) and then selling him for £90M has to be the most profit a manage had ever made selling a player
