I'm not an Arsenal fan, but a lot of my friends are and I found myself getting swept up with it all in the pub last night. I don't think there was much between either side and Villa's goal proved how tight the game had been. Arsenal then fell prey to Barcelona's "death by 1000 passes" manoeuvre but managed to keep their composure on the break which resulted in their goals.
It must be said thought that they were lucky that Song wasn't sent off. The referee was far too whistle-happy but, even accounting for that, I'm pretty sure Song made at least two tackles that warranted a yellow.
Also, I have to say that the commentators failed to give any credit to Arsenal's goalie who did in fact prevent Messi from scoring when one-on-one. They all said that it was Messi's fault for missing but, if you look, the goalie had covered all the "goal-scoring" angles, forcing Messi to chance it on the far post.
