I don't feel Napoli will be looking at the other teams around them at the top of the seria a, their mind will have to be on themselves, and not if the other teams are winning or losing, if they take their minds off themselves for even a short time they may lose their concentration and consistency, they only have to continue winning games, playing the way they are doing now and they will surely be champions at the end of the season. There are still many games to play, but Napoli have already set themselves as the favorites, and with the way they are performing in the champions league, they may be the 'small' team that goes very far and causes upsets in that competition this season.
Napoli are not a small team, they are strong mentally and they are also good in quality. Their consistency over the years has brought confidence among the fans about their good possibilities in the competition, but regarding the title then I think it still depends a lot on how they finish game by game.
Last season Napoli also played well and they also led the standings and competed with several other top teams, but in the end they failed to maintain the consistency that made Milan win the Scudetto at the end of the season. I don't know what the scenario will be this season, but Napoli are one of the favorites in Serie A which I might agree with.
