In my oppinion, the result was unfair. We deserved at least a draw and should have scored 2 or 3. The disallowed goal was a pivotal moment in the game, but the most critical thing was the terrible moves done by Guardiola.
As last year in San Siro, we lost the match because instead of going up and kill the enemy Pep decided to be deffensive. Putting Keita for Villa is the most stupid thing he could have done. Watching the match live I said to my friend "This is going to cost us the game".
Basically, we don't know how to play without going to the net. We don't know how to speculate with the result. And Keita is the most useless player in our squad. He can't get in the flow of the game, he's slow passing the ball and can't keep the position. It's not a coincidence that Arsenal had not shot to goal in the 2nd half until this sub.
Wenger played his cards and went offensive and I'm glad he did that and won. I hate cowards, so I hate when my team ceases the efforts. We did it last year at this same stadium, we did it at San Siro and yesterday.
Guardiola is a great coach, really, and I appreciate him a lot, but in the big matches it seems he's never in control, either the team plays great from start or he doesn't know how to change the match. In the other side, Wenger tried suicide but succeed. I'm glad football rewards bravery. Something we must note down.
I don't want to sound too harsh to Barcelona, though, we played a good match and were unlucky. The referee didn't help at all in key moments, but big teams must be over this. Messi was too selfish, Iniesta was very poor and Maxwell didn't know where the match was being played.
Not having Pique in the 2nd leg is very important. I said before the match that Arsenal could win and we were no favorites. I still think we are no favorites and Arsenal is the only team that can beat us playing at the same sport.
Other than that... what a great match for spectators! The best match of the year in footballing terms. So congrats to fans of both teams. That's how we love this sport.
