Well to be honest until last year there was a serious debate there, Vicky didn't have the best year though while Iker were more solid.; though that has a lot to do with the teams in front of them.
he was the one who kept madrid in this tie and deserves the most credit (unlike the goalscores that get all the credit as always) although somebody in the real madrid coaching staff should really teach him how to place a wall. he has made so many mistakes with it over his career, like del piero or senna's free kick as well which i remember right now.
