Yup, I'm also not saying they will be 100% unbeaten this season. However, Napoli performance so far is looks amazing, maybe they can still manage to keep their record in the upcoming 5-9 matches. If this is achieved, of course we will see the signs if Napoli will be the new champion this season. And we know AC Milan must be willing to lose Maignan due to injury while defending the French national team in the world cup, he may not be able to play in January this is a bad conditions for Milan, since Maignan is the key for Milan to become champion last season. Juve still need to prove their consistency which they have recently regained after struggling at the start of the season.
It seems that everyone is feeling very confident about Napoli's title success this season, but I may not be too confident about that at the moment. Napoli are proving to be a very strong team at the moment, but all of that is not much considering that Serie A is still quite far away and there are still many games waiting for them in the second half of this season.
I have seen how Napoli end season after season, they are a top team but it is still difficult to win titles. Right now Napoli are scary and very dangerous, but soon I think they will lose that consistency when their focus is divided on the Champions League and other important matches in 2023.
