Darmian ONLY made sense as a depth option, when we thought Barza will go, so he would be some sort of 5th fullback (can play both sides) and 5th CB (for a 3 man defense, dont trust him as a CB in a 2 man defense). but with Barza staying:
Chiellini, Benatia, Caldara, Rugani, Barzagli
Cancelo, AS, Spinazzola, De Sciglio
+ Cuadrado (RB) and Can (CB, for 3 man defense)
we are kinda stacked. if AS leaves, we need better.
