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.
Yes, Vicenzo seems quite interesting and might suit Napoli. On the other hand, there are several names that are also rumored to replace Spaletti, namely Conte, Gasperini, Enrique, and several other names. Of course, the tasks and demands of the next coach are also quite tough because at the very least, he should be able to help Napoli retain the league title and get another trophy if possible.
