Barcelona had all the possession because Manchester were playing a very defensive team. I think at Old Trafford the game will be completely different, with both playing in an attacking way which will open up the game a lot more.
I think Man United will make their way into the finals but it won't be an easy game, but in saying that, does anyone remember Man United 7 Roma 0 after a 2-1 loss in Roma
man utd will do better at old trafford...i have to admit tho, they are at a disadvangtage if barcelona do score, but the likes of messi where not enough to break united in spain, where the fans were going mad
