This season, Napoli have no hope of making anything happen, in fact they are having difficulty finishing in the European zone. If we trace it back a little, the beginning of Napoli decline occurred when they parted ways with Spalletti, and his successors Rudi Garcia and Walter Mazzarri failed to manage the club, leading to their dismissal. In the remaining matches this season, Napoli is just trying to finish in a better position, and who knows, they can get a ticket to the European Confederation League. Regarding next season, Napoli will face many challenges, especially keeping their star players from leaving.
If Spaletti stays, he will be sacked too because Napoli shown problems since late of last season. It's hard for a club like Napoli can defend Scudetto and Spaletti knew about that, only Napoli fans were too optimistic about capability of their star players.
When opponents in Serie A prepared better to control Osimhen and Kravatskhelia, Napoli lost most of their attacking power and this is start of their performances in general. Rudi Garcia, Walter Mazzarri might not do their jobs well enough but these coaches are not responsible for all negative things in Napoli this season. With several matches left, Napoli need to focus and aim at a position that is enough for them to at least join UEFA Conference League next season.
Napoli management is required to take wise steps in preparing for next season, apart from maintaining the existing squad they also have to look for a coach who suits the overall player profile.
This summer can be even harder than the last one as Osimhen will nearly leave and only future of Kravatskhelia is unknown. They even can lose some other star players to bigger clubs in Italy and around Europe.
