I also think that Napoli will still be very similar to last season, even though there will be slight changes at Napoli, it will definitely not be so bad for Napoli because they will still be one of the strong candidates in Serie A next season. Although I also agree more with what you said because before the season starts speculation for the Napoli team sometimes wouldn't be more accurate to say, so it will be better to see how Napoli do at the start of next season in the league.
I think Napoli's performance will no longer be the same as last season so they can secure the title again next season. Napoli have lost their best coach who brought them success last season, so the same expectations and quality will never be the same again next season.
I don't know too much about the new Napoli coach next season even though he has coached Roma for several seasons. Rudi Garcia is a coach who actually has a lot of experience in several Ligue 1 teams, but he hasn't had much success in his career. Yes I will probably doubt Napoli next season a lot, but that team still has a lot of quality players.
