Pep Guardiola will not join Napoli because he is on top of Premier League and Europe after last six successful seasons with Manchester City. He will not move to a smaller club like Napoli but it's possible for Mourinho to do this. With Mourinho, there is another barrier for Napoli to sign with him. He is experienced and smart enough to realize problems in Napoli so he will likely wait for chances from other clubs.
Haha you are right, it's impossible to see Pep Guardiola becoming Napoli coach. because Guardiola currently, like Mourinho, will prioritize a team that can meet the players' needs according to their wishes and whatever the price. If Napoli hopes for Guardiola, then Naples must prepare a big amount for transfer fee. I'm not sure Napoli can fulfill this. Moreover,
Reuters reported that Calzona is currently Napoli's new coach.
Oh, how stupid it was for Guardiola to leave Man City to go to Napoli. I don't know who can speculate on this story. Perhaps that is the nihilistic story of the Napoli Club. Guardiola is flourishing with Man City and has the opportunity to make history to win the successive treble. There is no reason for Guardiola to leave. There will be no magic for Napoli to get Guardiola. Even keeping their number 1 striker, Victor Osimhen, is becoming difficult. Recruiting coach Mourinho is possible, and of course, it will require a significant financial sum.
Napoli should not continue to make the mistake of randomly choosing a replacement coach. This only makes the club waste time and things become more serious. Napoli should spend a large sum of money and a generous invitation to recruit Mourinho. That would be better.
