Nothing wrong with a 3 at the back, if you have WB's like Cancelo, Cuads and Alex Sandro. Don't mix it up with a Licht-Asa 3 at the back. It's like day and night.
Cuadrado was very frustrating against Frosinone. Same with Bentancur. I hope they bring their A game today otherwise I see us going back to 4-3-3 and introduce Berna to save our ass again.
We have pretty important Napoli game, and YB game midweek where Ronaldo can't play, e.g. Mandzukic and Berna will start with Dybala. Dybala will hit the bench against Napoli.
It's fine, he's also experimenting. Cancelo on left, Dyb-CR7, Dybala in better role, CR7 as CF, and perhaps Berna as mezzala in 2nd half with protection behind him.
