i guess only 2 barca players had a good match: umtiti and messi. mascherano's game wasn't bad either for the most of the match, but chiellini scored a goal on his watch. also, andré gomes had a good impact on their game, he had like 7-8 tackles+interceptions during a single half, that's prime vidal level defensive work.
some of them like neymar, mathieu or rakitic didn't even show up.
