I think their squad is ok for 4312, as it manages to put their best players on the pitch in ok positions
Donnarumma
Calabria-Romagnoli-Mussacchio-Hernandez
Paqueta-Kessie-Bonaventura
Suso
Correa-Piatek
Squad fillers like Castillejo, Laxalt, Borini, Calhanoglu, who could be classified as wingers, will have to adapt to CM/AM/SS rotation roles
