Milan will really need to make a big improvement for next season. Because they didn't play as good as the last champion should have done. They couldn't even enter a title race with Napoli properly. They made so many unnecessary point losses and barely made it to top four. I'm saying "barely" because if it weren't for Juventus' punishment Milan were going to be out of top four.
Therefore Milan will need to learn their lesson from all of this. They did a good job in the Champions League though but they were very ineffective against Inter in the semi finals at the same time. I don't know what they can do there next time but their priority must be to remain in a title race throughout a season.
Could it be because Ac Milan was doing well in the Champions League that was why they didn't give too much attention to the Champions League knowing too well that Napoli had already overtaken them in the Serial A league chase.
I appropriated Milan's in the Champions League to Leo R absence in the first leg between Ac Milan and Inter Milan.
They got another opportunity to put their team in order to be able to contest for the title league coming season.
