Looks like I was a bit off the mark with Demichelis, albeit to be fair to myself when I said if City lose it would be because they are an inferior team to Barcelona and not solely because of Demichelis I didn't expect him to get a red card and give away a penalty.
With that said City looked great but Barcelona hardly got out of a second gear so its six of one, half dozen of the next. It also has to be said that this was the first time I can remember Barcelona winning an away match in England in the knockout stages.
Some City players were fantastic for them in an attacking sense, Fernandinho and Silva in particular, while others were either isolated (Negredo) and some just not in the game (Navas)
City are getting praised in this "The little engine that tried its very best but just couldn't.", especially during the match on commentary. Of course their efforts are to be praised but if I closed my eyes and just listened to the match I would have thought that Everton were playing Barcelona and not a team that was assembled for 500 million pounds, full of internationals, on for the quadruple and favourites for the premier league. People can't have it both ways, either City are a mega-force and best team in the world which makes a result like this a massive disappointment (let's not forget nearly everyone predicted a City win here) or they just aren't one of the very best teams in the world and people have thoroughly overstated their capabilities.
I'm not trying to say that City are an awful team, just pointing out that even before this result people were too quick to declare them the best team in the world.
Back to the game, I can't believe how lackluster Barcelona were. At times there was no movement at all in their game as they just stood there and passed the ball to each other staticly. I'm not sure if they just underestimated City or if it was just tactics but it didn't feel like I was watching Barcelona. Even though they weren't at their best they still managed to cut City apart on a few occasions, the offside chance, Alves marauding down his flank and a couple of close chances. One thing I didn't understand was why they kept whipping in crosses, Kompany and Fernandinho had each and every single one of those for dinner. I can't remember a Barcelona player winning a header in the City penalty box so why keep trying it? Anyways they got what they want, clean sheet, 2-0 win.
City did well I thought, pushing hard for an equalizer even when they were down to 10 but Barcelona just look like they never got out of second gear and when they went up a level, City couldn't live with them, see that period after their goal. It wasn't a humiliation by any stretch and City did themselves proud but it was a lesson in humility, a lesson of we're good but we aren't that good yet.
EDIT:
Surprisingly enough, I just checked the stats and Barcelona had 68% possession (big surprise) but they also had more shots on and off target, which surprised me somewhat. Someone just looking at those and the scoreline would think that City got battered but that wasn't the case.
