Our defense do not play/move as a unit, and yes, Chiellini is a part of that unit and shoulders some of the blame as well. I don't see how any1 can argue otherwise when you look at the stats. When the numbers are that bad everyone is culpable.
That doesn't mean Chiellini is shit though. Individually, he is a beast. Strong tackler, great marker (Ibra said he was his toughest opponenet), good in the air, difficult to beat on 1 v 1's, etc.
Just like the rest of our players who either excel on international duty or show their worth at other clubs, Chiellini is struggling as well. Once we have a proper coach, all the doubters will see his true worth.
