I was only able to get out of work for the second half, but really, Derek Rae and Tommy Smyth kill these games for me; ESPN's coverage is always so biased towards the EPL teams, that it makes listening to these matches almost unenjoyable. If an Italian team had played the way Chelsea did today with 10 men completely jammed behind the ball, it would have been "anti football" and "uninspired", but when it's Chelsea, it was described by the announcers as a "defensive masterclass."
Barcelona had something like 70% possession, and 19 shots to 3. In the second half I watched Chelsea concede numerous dangerous free kicks around the penalty area. Alves hit the top mesh of the net on a FK that just curled over, Bojan missed an empty net with a header on an absolute gift of a cross (Alves again), and Cech did well to fend off an absolute bullet from close range (on the right side... Can't recall the player at the moment - I was eating). Hleb was all alone with the keeper on the left, and again Cech was in perfect position and made a great save, Eto'o also had an opportunity where he was just about all alone in the center, made a nice move on the recovering defender, but really waited too long and Cech had a relatively easy save.
I didn't see the first half, but for me the second half was all about Barcelona not taking there chances - big props to Petr Cech for this draw. Chelsea barely got out of their own freaking half.
