Yeah, the CB department is indeed stacked, but Barzagli - at 35 - will probably not be upset if Max opts for Benatia from time to time. At Barza's age, players tend to accept squad rotation alot more. As for Chiellini, we know how injury prone he is, so I'm sure everyone will get to play a decent amount of games in the end. Rugani is a legitimate concern, though.
