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.
