Indeed Ac milan qualified for the Champions league this season none other than the luck of the point deduction received by juventus which allowed Ac milan to maximize this opportunity as best as possible. If you look at Ac milan performance this season, I dare say they performed quite badly because they didn't win a single trophy this season.
What happened with Juventus gave AC Milan a good opportunity to be qualified for Champions League group qualification in 2023 - 2024 season. In general AC Milan did not play too worse than Juventus and without the point deduction on Juventus, two clubs are already similar in total points they got. Their rankings are only different by one or two matches with win or lose results.
Ac milan was knocked out by inter milan from the Champions League and it hurts a lot if we see because they lost ower two leg and also Ac milan was knocked out by inter milan in the Italian Super Cup final this season.
I don't consider it is a bad result. If AC Milan can beat Napoli in quarter final, it's possible for Inter Milan to beat AC Milan in semi final. Those clubs are not too big different in quality and in only two knock-out matches, everything can happen like AC Milan surprisingly won over Napoli and Inter Milan won over AC Milan.
They will comeback in a next season of Champions League. Did we say AC Milan have DNA of Champions League and it helped them to win over Napoli in quarter finals?
