I expect if this transfer gonna be a complicated transfer as napoli's president will not even let him go to the manchester united.
Napoli will not be coached by spalletti next season. This is the main key why napoli will not be able to repeat the same performance again like this season. Im not expecting napoli will be able to win scudetto again next season.
Juventus has been leaving from its problem and it will come back stronger next season to win the scudetto agian.
There are so many team will be doing massive improvements in this summer transfer season.
I think that the way for napoli to defend its scudetto will become even harder next season.
Juventus is likely to be the main competitior as it will not get same problem like this time.
Most likely it will be difficult for Napoli to defend the title because without Spalletti they will not be strong enough to stop other teams like Inter Milan or Juventus next season. Several other teams will put pressure on Napoli in defending the title and one of the teams that I think will be quite strong next season is inter milan.
As far as I know, Spalletti is still working for Napli there is not any problem for this coach there, Spalletti had a good performance and he got the achievements he wanted to get.
More than anything Napopli needs to keep the players they have for another season and thy also need to hire an alternative players for stars they have like Osimhen.
