I have to agree with Bojan that Puyol's performance against Villareal was below par. He looked shaky at the back, maybe it's due to partnership with Pique. I think he was complacent.
Re: 10 - Lionel Messi
Messi had a quiet game in my opinion. He did not shine like the game against Real Madrid. Maybe he's tired? I notice he's pretty greedy in this game. There was an instance where he should pass but he didn't.
Re: 3 - Gerard Piqué
It was silly to be red carded on such important match. His first half performance was average. He made too many silly fouls which led him to the red card.
I did, but only for 45 minutes. Both teams have an attacking mindset from the very first minute. LDU de Quito played well, they must be proud with their performance.
