Roughly speaking, Inter, Milan, Juventus, Napoli will take 4 tickets
Why did you include Napoli in the team that qualified for the Champions League? Inter, AC Milan and Juventus are right because they have already locked tickets to the UCL next season. But Napoli is the team ranked 10th in the current standings. The teams in the top 5 have now confirmed their tickets to the UCL because their number of points can no longer be caught by other teams.
I'm also not confused, what does this mean for next season? because this season, Napoli have really failed, in 10th position, and that is a very bad thing, dropping from the title holders to the top 10 only. Meanwhile, those who enter the UCL are definitely those listed in blue in the standings. Meanwhile, Roma, with its new coach, de Rossi, has actually experienced quite good development this season. Even though they couldn't enter the UCL match, at least they managed to finish in the top 6 and re-enter the Europa League. In fact, their performance was quite doubtful in the beginning to the middle of the season because it was quite bad and there were several problems before de Rossi took over.

As for Napoli, I don't have the right words to describe their performance so far and obviously everyone knows how bad they are. The change of coach was the start of a disaster for Napoli and this fact was proven by the lopsided results they got. There is nothing special they should be proud of this season.
Apart from that, if we talk about Roma, to be honest, they have actually experienced significant improvement since being handled by De Rossi and if they don't immediately take quick steps by sacking Mourinho, it is likely that they will remain at the bottom of the table as happened at the start of the season. The club management has realized this and is moving quickly to overcome the existing problems and that is a step that should be appreciated.
It's been a very disappointing season for Napoli fans this season, they really have to see that the club they love is not in the European zone even though they are the defending champions, but Napoli are helpless in some of their matches, Napoli have lost their concentration and consistency, so that's why they are often unable to win important matches, this season has been a bad season for Napoli, of course it is very sad to see the condition of Napoli, but whatever Napoli is experiencing, at least it will not happen again next season. There must be changes for next season so that they are able and compete in the class. top flight with big clubs.
