For Milan this season will probably not have a happy ending and certainly not a comfortable one in the last three games. Even Lazio got lucky now that AC Milan failed to win again or otherwise they could have gotten into trouble as well. Now it seems that the first four ranks are almost certainly taken by the top four as per current standings in the table. I wouldn't expect any changes from here on and for AC Milan the next seven six days could be very ugly if they get eliminated from the Champions League and then Lazio perhaps win their game in the Serie A or even tie it, the dream to qualify for the biggest European club tournament will also slowly but surely come to an end.
Yes, Milan will most likely end the season very disappointing. I saw that Milan made quite a few unforced errors which impacted their targets in Serie A. The Rossoneri's move will be even tougher because they must allot their focus to the Champions League. I saw that Pioli was very nervous in preparing the team when faced with such a precarious situation. He should have maximized the match against Spezia and not save a number of his main pillars. In the Champions League, Milan's chances are very slim, although they are still optimistic that they can catch up with Inter. I predict that Milan will fall in Leg 2 and the steps in Serie A will be tough in the remaining three matches.
It is very unfortunate that at an important time at the end of the season, like now, AC Milan is experiencing a decline in performance, but in my opinion, this is inseparable from the injuries to several of their main pillars, so this has had a big impact on their performance.
and Pioli's big mistake was when they forgot about Serie A and were too focused on Champions League matches even though their competition was still quite fierce and they still had the chance to finish in the top 4 but in the last 5 matches they only got 2 wins which made their chances even smaller .
