Don't think there is a team in the world who you can say has a "much better" defence than ours.
As a team they do really well to press, close spaces and limit counters. But even today their defenders showed how vulnerable they are when put into space. Dante and Boateng can't do half as well as Barza and Chiellini in a simple 1 v 1 in space. Honestly, Dante possibly should have been sent off for two challenges where he was left 1 on 1.
