Barca come to Old Trafford knowing that scoring once may be enough to see them through, if they can keep the game tight in defence and concede at most once themselves. If Barca score the first though and try to shut up shop then it's offering Mancheser United the chance to throw everything at their defence, which is arguably the weakest part of their team. Barcelona are known for their attacking players in Messi, Eto'o, Henry etc, not their defenders. Manchester United are missing Rooney but Tevez, Park and Ronaldo all have the ability to cause nuisance.
I can see Manchester United scoring first, Barca equalising so trying to defend but caught out to a 2nd goal, Barca push forward and concede a 3rd and the game is all over.
