Milan are the weakest out of the four teams IMO.Manchester United go in as favourites against them because Ronaldo could murder their ageing defence line with sheer pace.Having said,Milan have the expereince to tame Manchester United.They did it two season ago with Shevchenko injured in both legs if i remember correctly,though at that time Christiano Ronaldo wasnt in such great form.But maybe Milan's status as the underdogs in this match would serve them well as they'd hit the other team when they are least expected to,just like they did to Bayern when a lot of people including myself thought that Milan had no chance.
Manchester United winning the CL would be more sickening than Milan winning it.Just watch how the english media sucks up to Man.Utd if they win it.Milan's victory will be much more bearable for me personally,and good for Italian football generally.
