Agreed, but I havn't seen an english team put real pressure on Barcelona or Real for that matter in quite a long time, last time I really thought they would lose was the final back in Paris, but then Henrik Larsson turned it around.
To be honest, only an arsenal fan could blame the ref in that match serie, the ref in the away game for arsenal was pretty shakey, Barcelona had a penalty in that game that wasn't given but was quite clearly a penalty for anyone who saw the replay, then there was the sending off of RvP, he had been forgiven two textbook yellow cards prior to it, he had it coming, and could(should?) have been sent of earlier then when he was. Getting sent off for taking a shot after the whistle is silly in such a game but as I said, he shouldn't even be on the pitch at that point since he had done things that warranted a red card earlier in the game, if I remember correctly there should have been a 2nd red card in the game as well, the arsenal defender that caused the penalty.
Edit: and had Arsenal gone through, it would have been a real shame, they had what 1 shot at goal at nou camp (which didnt even had to be saved since it went wide)? 30% ball possession and generally created zero threat or chances, they were massively outplayed.
