It's still too early to judge which team will win the title. Napoli have indeed been able to perform exceptionally this season, but the distance with AC Milan is only three points adrift, as well as other teams who also have the same opportunities even though they sometimes appear inconsistent. We should know, Serie A this season is quite competitive, I predict the title fight will be decided until the end of the season.
It would be better if the winner was determined until the end of the season because it would continue to make the competition between teams fiercer this season and make Serie A more attractive to the audience. The curiosity as to who will be the champion will obviously exist, because the more competitive a League is in terms of winning the title, the more spectators will watch every match for big teams such as Napoli, AC Milan and others.
