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.
