He had some minor mistakes, but holy shit he saved our asses when it mattered! Overall he was quite good...
One thing I've noticed is how he rushes to head balls that are clear he can't reach on time, it's not the best of examples but look at their goal... I'm not saying it was his fault because I believe he had nothing to do with it, it's just that kind of play, it happened against Sociedad too, which is a way better example...
