Milan can enter the UCL zone if he can handle the next Big match well. Milan must win against Atlanta and Juventus to be able to lock a ticket to UCL.
But in my opinion it is almost impossible for Milan at this time to enter the UCL zone, from the remaining 5 matches apart from facing Juventus and Atalanta, they will also be troubled by Torino who are playing at home, as well as Cagliari and Benevento who want to get out of the relegation zone.
Benevento, Cagliari and Torino have 31 points. It is very difficult for AC Milan to win easily in their remaining 5 matches.
