As far as I can see, Milan's performance is not entirely consistent, the draw they got when they faced Roma at San Siro can explain everything. Overall, their performance has improved a bit since the change of coach. Now they are far behind Napoli who are currently at the top of the standings, it is difficult for them to achieve that target.
In my opinion, this season it is a bit difficult for Milan to return to the top four, this is because the performance of Napoli, Atalanta, Inter and Lazio is still very consistent.
Milan has lost a lot of points at the moment, they are behind in points and all they can do is try to catch up with the points difference to be able to enter the top 4 position. Even if it is too difficult for Milan, at least they have to get a position for the Europa League or Conference League.
we have to see what happens to them this season because it is not easy to compete in the top 4 standings. They have to do their best for their position next season.
