He literally couldn't do anything tonight. Messi has spent 95% of his career playing in possession based teams. Even someone with his unrivaled abilities can't do much when he barely gets enough touches in dangerous areas. He was feeding off mostly scraps tonight.
poor composure(too relaxed?) when in front of goal and was in walking mode tonight.
compared to that desire from the first leg...
meh, for how completely lazy he was without the ball he needed to do more. a couple good passes in the first half was not enough. basically gave up in the end.
He bottled that big chance in the first half. If he scored that, the game would be over.
He can`t be absolved from blame today, but I agree that he`s the last one that should be criticized.
