I do think they deserved to be in the final when looking at the way they play football. Although some of the decisions made against Chelsea were awful. Yet Barca should have had a penalty in the first leg. It swings in roundabouts although I do see what you are saying.
At least Barca haven't had a rich sugar daddy take over and turn them from a non-existant club into league challengers (like Chelski). Fair play to Barca on the night as I think they have been the best team in Europe all season. They could only play what was put infront of them and they could only accept the decisions made by the refs.
Barca should have had a peno i the first leg, I agree. But it doesn't really matter when you probably need to use 2 hands to count the amount of penalties Chelsea should have had!
I think that's a bit harsh on Chelsea. Barca have a tonne of money and always have, just because they've been a richer club longer than Chelsea doesn't mean they haven't bought their way into the Champions League, they have, same as most top clubs.
Watching Barca today, they seem unbeatable. On the ball it's clear to see how good they are, but it's off the ball that's amazing. Everytime United got the ball, they just chased it and gave no relent until they won it back, amazing stuff. What a year for Xavi and Iniesta.
