There has been a decline for AC Milan this season and it looks much worse for the Serie A competition and if the current poor form is not improved then it is very likely that next season AC Milan will not be playing in the Champions League or the Europa League. AC Milan have been going downhill for a few seasons and this season looks much worse, even though if you look at the quality of the players they have it is not much different from the last few seasons. There needs to be a big evaluation for AC Milan and if it is not done soon then they are in danger of qualifying for the Champions League or the Europa League next season and that is very detrimental for them.
Yes, it is undeniable that Milan's performance this season is indeed very bad. So if Milan's performance continues like this, I am sure that next season Milan will most likely not qualify for the UCL or UEL. Because, currently Milan is ranked 9th in Serie A and has a fairly large points difference with the teams in the top 5. So with this, of course it will be very difficult for Milan to get tickets to the UCL or UEL. Therefore, the only way that Milan must do now is to improve its performance. However, if you look at the quality of Milan's current players and also Milan's coach, I personally do not see any positive developments. Because, it is proven that since the beginning of the season until now Milan has never been seen to have an epic performance in its matches. So it is clear that Milan's current coach is not providing good development for Milan. 
In addition, next week Milan will face Lecce, I think in this match Milan must be able to get 3 full points. Because we can see that Milan has a less than good record in the last 3 matches. Because all three matches were obtained by Milan with defeat. So if in this match Milan loses again, I think it will have very fatal consequences. Because Milan's ranking could drop and will be further away from the top 5.
I personally also feel a little disappointed with Milan's performance this season because indeed with their new coach Milan's performance has always been less good and in my opinion Stefano Pioli is better at coaching Milan because last season Milan managed to reach 2nd place. but this season of course there is no suitable coach to replace Pioli. yes of course now I also think Milan will have difficulty getting tickets to the Champions League and Europa League. but it seems that if Milan does not qualify for the UCL and UEL it would be better if Milan looked for a new coach to be able to make Milan even better.
it is true of course if Milan loses to Lecce of course it will potentially make Milan drop in ranking. but in my opinion in the match between Lecce and Milan I think Milan will have the potential to win and it seems that in that match I will bet on Milan because of course if you look at the standings of course Milan is far superior and I see H2H Lecce has never won against Milan in its last 5 matches.
The Milan season can really be considered a slaughter, the management of the company and really painful, seem that they do not know what is done to manage a company at best, the game against Lecce will be an easy game for Milan but given the team's form of the form I don't think you can expect a victory
