At the beginning of the season it is indeed very difficult to predict but if Napoli continues to experience a decline in performance losing points in the next 5 matches, Napoli will definitely be out of the title candidates this season.
I believe Napoli no longer has the qualifications to compete for the title this season. Last season alone, their performance had already declined. Last season Napoli had to finish in 10th place in the standings. Not a good position because they were previously champions.
Now they have started the season badly, and I am sure it will not be much different from last season, or maybe even worse.
Seeing the match against Verona, which was even below Napoli last season. And now they have slaughtered Napoli 3-0. Playing very dominantly with ball possession, but easily throwing away opportunities to score. Clearly, that is a hard blow to the mentality of Napoli players.
