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.
I remind you if spalletti will be leaving from napoli in summer. Napoli itself is still searching for the new coach to replace him. It seems like that napoli's management doesn't feel satisfied with napoli's result won scudetto.
Napoli's president has even confirmed it in his interview. I think that if some players are gonna leave from napoli too following what will be doing by spalleti.
Let's see what's gonna happening with this club in summer. There will be a lot of surprises to come very soon.
