Personally, I think Allegri could get him in as a TQ in a 4312. OR Christmas tree formation behind the strikers.
Maybe...
Bear with me...
Buffon
Licht-Bonucci-Chiellini-Sandro
Khedira-Marchisio-Pogba
Gomes-Berardi
Dybala
When all are fit that would be lovely. Morata can play either as main striker or behind the main striker. Gomes can slot in for Marchisio until he is fit and Morata in for Gomes during that duration.
