This season, Napoli is still very serious about defending their Serie A title, by keeping Conte at the club, this is one of the very good capitals. With the signing of de Bruyne too, then, there are some of their signings along with quite good rumors in the future. So that makes Napoli still look confident, but let's see.
Napoli is really still trying to be the leader next season, you can see it from the effort they are putting into the transfer campaign and how they are keeping key players
Of course he abandoned some of them on the street like Victor Osimhen, but others have arrived and they are strong too.
At least, Napoli has extended Conte's contract at the club for the next 3 years, this is the right decision so that they don't lose another good coach who made them champions like before when Spaletti was there. That's what made Conte stay in Serie A, one of the reasons.
And now, they are collecting some more tallenetd players, some of them are younger and stronger strikers, and strengthening their defense well.
