I posted about my experience at the Barça game last night on my blog:

The Barça Crazies

I have been to a Bruins-Habs playoff game.  I have been to a Patriots game ending with a Tom Brady game-winning drive with 22 seconds left.  I have been to a Red Sox playoff game in which David Ortiz belted two home runs. But nothing compares to the atmosphere of the FC Barcelona game I went to last night.

Walking to the stadium, I knew it was going to be a breathtaking experience.  There was energy in the air as Barcelona was about to take on Manchester City in a Champions League match.  People were yelling all the way from 10 blocks away.  The Man-City faithful were drunkenly singing about their beloved team.   But their cheers were drowned away in the thousands of Barça fans funneling their way into Camp Nou, the Barcelona stadium.

The view after stepping into the stadium was jaw-dropping.  The Barça fans filled in the seats.  By kick-off, the stadium was packed with some 85,957 people, more than twice the size of Fenway Park.  I was surrounded by all Barça supporters.  It seemed like the whole stadium was, except a few sections in the highest seats filled with Man-City fans.  Those fans seemed helpless; cornered way up high with no where to go, no one to help.

The first half of play was relatively uneventful.  A few yellow cards for Man-City, but no goals for either side.  But a little into the second half, in the 67th minute, Barça star, Lionel Messi, fired one past Man-City goalie, Joe Hart, to go up 1-0.  Camp Nou exploded.

Here is a video I took of the goal:

The stadium stayed electrified for the remainder of the game.  At every close call the referees missed the stadium would erupt with whistling, which I figured to be the equivalent to booing in US sports.  Every time Barça would make a poor play the fans would toss their arms up in the air in disbelief that their players could ever make a mistake.

The stadium stayed glued to their seats until the final whistle, Barça taking a good match 2-1 and winning aggregate 4-1.  The game was a spectacular experience.  ¡Vamos Barça!
