In as much as Napoli player's will take some time before they adapt to the coaching pattern of their new manager Rudi Garcia who replaced Luciano Spalletti after the latter stepped down from his role as the club manager, I think they can still do well this season or probably retain the Italian Serie A title with the new manager.
Their performance last weekend is a proof that the players are already doing exactly what the new managers demands of them and with their lethal and clinical Nigeria striker Victor Osimhen at his best, Napoli still has all it takes to retain the title
Seria A will be more competitive than last season, Napoli will fight to retained their title, not an easy route for them to take. Napoli will not win the Scudetto two times in a row, it's not possible, probably not under the new coach, Rudi Garcia. He needs more time to adapt to the club and the players, basically there's enough time for the new boss to implement a solid winning strategy. Victor Osimhen is a top player that needs to get all the necessary goals and assists he could possibly lay his hands on, because there's absolutely no time for reluctant actions.
I think it is too early to predict if Napoli won't be available to win Scudetto this season, as far as serie-a is concerned this season Napoli is the most favourite to become the Champions for the season. Looking from the games Napoli have played so far for the season their performance still look lusty and outstanding, I don't think any other team in the Italian league will be this very strong to challenge Napoli from winning the league, Napoli has one of the best striker that is very good in scoring goals.
