For next season, it is certainly difficult to predict who will be the best, because almost all teams will evaluate their respective teams. I think it's too early to judge the team's prospects for next season.
I believe if napoli will not be performing the same like this season. it's caused by spalletti and some important players will be gone.
The power of napoli will be decreasing a lot. Spalletti has internal problem with napoli.
That's why he was not even extending his contract with napoli. Napoli will be playing so badly next season.
I think it depends on who the players leave and it depends on how Spalletti manages his players because as we know the current situation for Spalletti he is one of the smartest coaches in Serie A.
Last season actually proved how shrewd he was in spending and reshuffling players, especially I think many people were initially unsure, including myself in Spalletti's decision to let go of their core players like Dries Mertens and Koulibaly at the start of last season but he believed so much themselves by replacing them with young players.
It is possible that this season will be like that. Kim is most likely to leave but for others it is still uncertain so we just have to see how the transfer goes this time for Napoli.
