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.
It would be a perfect record if they managed to maintain an unbeatable record and it might just be the only one in Serie A history
Napoli started last season when they finished in the top 3 and this season they have continued to improve by continuing to secure first place.
Basically, no matter how much consistency and or dominance a team has in a league, they will still get lost even if it's only one or two defeats. The point is, there will always be moments where they get a busy schedule with difficult opponents. This will make the player rotation not run well, especially if many of the main players are injured.
But apart from these factors, I personally don't doubt the quality of Napoli this season and those who say Napoli won't win the title this season, I think that's not true.
Because after all, I am also aware of Napoli's development from season to season and also, there are still other teams that from season to season get good results at the start of the season. But as time goes by the team continues to fall and that team is Atalanta and even, previously someone predicted Atalanta can win the title.
Even though the fact is that Napoli are better than Atalanta and with this big difference in points, then of course Napoli will be able to have better morale to maintain its position at the top of the standings.
