There is the name of Vincenzo Italiano who is now being rumored with Napoli and it is said that there were some conditions under which Spalletti said that Vincenzo Italiano could be one of the worthy candidates to replace.
But indeed this is still confusing, especially with the current conditions that Fiorentina also emphasized that it is hoped that Vincenzo Italiano can stay at Fiorentina.
Vincenzo Italiano, in my opinion he's so smart. He was able to bring Fiorentina to 2 finals this season, although he failed in these two finals. But this coach's record is really good, if he have a great and strong squad like Napoli, then he can certainly bring Napoli to win the Scudetto again. Moreover, Spalletti recommended that man. But yes still confusing and also decision is up to Aurelio De Laurentiis, if him found another coach with more experience at UCL, I think that would be better because their target next season maybe also UCL trophy.
