If someone were to tell me that: Chelsea would come back from down 2, and draw at Camp Nou against Barcelona, playing a man down, and Barça getting a PK during the process, I'd be like: OK buddy, maybe enough with fiction movies. Now I now why it's called the beautiful game.
I understand where you're coming from SS, as Barca was clearly the better side. I gotta give Chelsea credit though. There is a reason why the games are played. With 10 players you shouldn't have expected equal possession/scoring opportunities. At the end Chelsea scored 3 times (twice at Camp Nou). That's usually enough at such a high level. Barcelona have no one to blame, but themselves. At the absence of Pique, and especially Abidal, it was obvious that Alves, and Puyol aren't high class defenders, and Valdes is mediocre at best. If your opponents come seriously only a handful of times, and scores at such a high rate, maybe it's time to point the finger at yourselves.
