I am sure Conte will be able to give his best and make Napoli a champion contender again. Conte is one of the best Italian coaches I know and he really understands the character of football in Italy. I agree with what you say that Conte must adapt to the character of each Napoli player and the club management must also give Conte a sufficient budget to spend on players who suit the tactics he will use next season.
Antonio Conte is indeed a great coach and he has good experience in Serie, he really understands Serie A because he also comes from Italy, but to build a team that has fallen like Naoli is not easy, let alone being able to make Napoli compete fiercely for the Serie A title. I think that won't happen in Antonio Conte's first season as Napoli coach, everything needs a process and time.
And Napoli is not a team that has strong finances to be able to bring in many talented players to boost the team's performance, so let's be realistic and I'm sure Napoli next season will only compete for the top 4 positions, not for the Scudetto.
