Yep, Allegri is in a tough spot. He has talent, but this talent is based on young players who will either have to assume new large roles on the team (Pogba, Morata, Pereyra, with Pogba already struggling) or new guys who just came in (Dybala, have to see Lemina).
His job is to carry this transition as smooth as possible, assure new and young guys.
We don't have natural players for no scheme right now (433 lacks LW, 4231 lacks LW and AM, 4312 lacks AM, 352 lacks RWB - Cuadrado is probably not one, 442 is not really used anymore in football as midfield gets too thin).
So just keep 4312, improvise Pereyra/Hernanes/Dybala as an AM.
Go with Morata and Dybala as starters. Morata deserves to be a starter from last season, Dybala meshes better with him than with Mandzukic, we need Dybalas characteristics. Just do the basic stuff. Forget fucking 352, specially with Evra and Padoin on the team.
Go with:
-------------------Buffon----------------------------
Licht-------Bonucci------------Chiellini-----Alex Sandro
-------------------Marchisio---------------------------
--------Hernanes--------------------Pogba-------------
-------------------Pereyra-----------------------------
-------------Dybala------------------------------------
---------------------Morata----------------------------
If Dybala offers what he can, will be in good shape.
Bench: Neto, Caceres, Barzagli, Rugani, Evra, Lemina, Sturaro, Mandzukic, Zaza.
Not considering Padoin, Asa, Khedira.
We definitely need more in the bench, have no good options. Coman would have been important for that.
But this is the best starting 11 we have IMO.
