3-5-2 is not happening at all. Allegri fielded a 4-3-3 and a 4-4-2 in friendlies and that's how we're going to play. These are the two formations that suits Ronaldo.
We can't field 3 CBs without Bonucci, because he is the only one trying long passes. Barzagli and Chiello suck at it Benatia, Rugani and Caldara prefer sort passes too.
Can could work there and any other CM, like Bonucci.
With Bonucci back, we will surely gift him a starter's place and prolly make him cpt by next year. He is Max's favourite son, he never hesitated to hide this favorism,a favorism not shown to any other vendetta we owned, like Dybs, Pogba or Higgy.
So he will surely select a formation that fits him the best and makes him shine as much as possible, like he always did.
This has been Max's favourite system, he tried many others, but always returned to this. Getting Bonucci back, is obvious that it leads into a new BBC, with Benatia taking the place of Barzagli, Benatia a player who was never given a chance, when we had Bonucci... Rugani too, this will surely create tense and inevitably issues, it doesn't help that Bonucci feels the favorism and with his characteristic arrogance will blaim everyone by himself.
Bonucci was always Max's priority and the sacrifices we are making to get him back prove that he still is. A player that betrayed us, left us and made us crawl back on or knees when demanded to return, he gave the power to Milan to demand a second Romagnoli as a gift and we didn't even blinked.
