Did you know, basically Milan is the only team in Group F that so far has not had any wins at all. Therefore, it is clear that Milan in the Champions League does not have a good chance of qualifying because after all, group F is the hell group in the Champions League this season. Moreover, basically Milan is a team that finds it difficult to be consistent every season. Even though Milan is in the top zone of the Serie A standings, but Milan can still fail when playing against mediocre teams. So yes, it is not surprising that Milan has no chance of qualifying for the last 16 in the Champions League and also, to finish in third place is still difficult for Milan.
Of course, this is a hellish group because it is inhabited by representatives of great leagues. All teams still have hope of qualifying for the last 16, but it's true, as you said, AC Milan's chances are very small, in fact they will most likely continue to be in fourth place.
In the next match they will face PSG, which we know is that PSG is now back in a good trend after winning in League 1 which made them return to first place in the standings. Of course this will be good capital to face Milan, especially since this match is played at PSG's home ground, of course this will be more capital for PSG to achieve victory against Milan.
