Not much I can say after reading this thread but congrats to City for winning the Champions League.
Seriously though the only tactical mistake I thought Fergie made was starting Hernandez instead of Nani. Not much use for a poacher center forward the way the game unfolded, and it wasn't exactly a surprise it unfolded that way. To stay on the pitch with Barca you need a proper set of midfield destroyers and United don't have one in their entire squad. I'd put this Barca team up against Figo and Zidane's RM, Sacchi's Milan and Cruyff's Ajax. No offense to anyone but to compare this game with the FA Cup Semi Final flatters both City and United.
