Would actually like to see Bernadeschi find the form he started the season with. He combined best with Ronaldo by far to start the season. His brief injury really was a setback for him.
That's why I would be curious to see him as a CAM behind Ronaldo-Mandzu/Dybala. I think he suits the CAM position better than Costa (who is a far superior winger to Berna). 4-3-1-2 or even 4-2-1-3 with Berna playing in the hole would be interesting for getting us creating through the middle. The latter is tough because Pjanic doesn't really suit that mid 2. If we had someone like Saul Niguez, would be amazing imo.
