Our starters this year were always gonna be Chiellini, Bonucci and De Ligt. Demiral was there just in case of an injury crisis in defense, while Rugani was supposed to be shipped off and we kept him only because there was no buyer.
After Chiellini got injured, it was normal to play Bonucci-De Ligt non stop, in order to build a chemistry. They can both make mistakes here and there, but we will stick with the captain and the record defense purchase.
As for Demiral and Rugani, they were gonna get very little playing time, as they do. Demiral screwed his first chance and then Rugani got a chance. Now Rugani screwed too and the next time one of BonBon or De Ligt is out, Sarri will probably pick Demiral.
