As reported by Manuele Baiocchini of Sky Sport 24, Fikayo Tomori is tired and may not be able to start for Milan at the moment. Therefore, we could see the Kjaer-Romagnoli's center-back partnership tomorrow against Udinese.
Calabria also has a slight fatigue and he is in doubt for the match, one of Dalot and Kalulu could replace him.
In the offensive phase, there could be changes also with Castillejo coming in for Saelemaekers to join the attacking trio of Rebic, Diaz and Leao.
Probable Starting XI: Donnarumma; Kjaer, Romagnoli, Kalulu, Theo Hernandez; Kessie, Tonali, Diaz; Castillejo, Rebic, Leao.
