People who said Napoli are weak, maybe they haven't kept up with Napoli progress in recent seasons. They have performed well in several seasons, just they are still haven't been able to win a championship title. There are many factors that makes them fail including consistency after break/half season that may has been solved this season. However, Napoli performance this season, made me remember what Milan achieved last season. It could be that Napoli's unbeaten run from the beginning of the season until now is the right time of the success from team development they have done in the last few seasons.
At the beginning I was also pessimistic, because usually there are always surprises at the start of the season. But this time Napoli has provided enough evidence, they are strong candidates to win Serie A this season. Of course declaring him the current champion is too early, because there is still a chance they will catch up with their points. But it is true that Napoli in several seasons have always been in the top five and that is the warning they are showing at this time. Let's see until the end can they survive.
In the 2017/2018 season and the 2018/2019 season they successfully finished runners up, in the 2019/2020 season they experienced a decline and even had to be eliminated from the Europa League zone. But in the following season they managed to slowly climb back into the top 5 and the peak was in the 2021/2022 season they could have won the Scudetto title if only they didn't have problems towards the end of the season. And this season they started very well by being at the top of the standings with 8 points ahead of second place. Too bad when they are not able to maintain what they have achieved so far. Their level of consistency will be questioned again if they make the same mistakes as last season. Also I consider it pointless if they drop out of title contention even if they started really well. Because the end of the season is always a struggle for clubs who want the title.
