The way Napoli has started this season, no other team looks likely to win the title. AC Milan is the Second in the table. AC Milan is also 8 points behind Napoli. On the other hand, Inter Milan is 11 points behind. More important than just how far behind the other teams is, Napoli's performance has been remarkable. They are consistently playing well in every match. If Napoli can maintain this consistency, other teams have no chance of winning the title. But if Napoli loses the truck and drops points in several matches in a row, Milan and Juventus have the potential to finish at the top of the table. But I think Napoli will be championing this season.
Napoli started this season very well and none could even imagine this team to winning the cup even if know the season is not finished yet AC Milan is far from first place and I don't think they will take the extra 11 points, however since we are talking about football nothing is impossible even in Serie A with this situation.
Also, they have players Victor Osimhen who can be the next world start if he continue playing like this, maradona's team. he can be the next start for his national team too.
