What do you mean by this?
I see they have played so far 27 games, 11 more to go. So when were they crowned champions? Or you are one of those folks from the future? Hahaha

Do you doubt that Napoli became the champion? In order to "officially" complete the title, they need to score only 14 points in the remaining 11 games. And this is provided that Lazio will not lose points. It seems to me that in about 4 games Napoli will officially become the champion because Lazio will not win every game, and Napoli just need to be no worse than the pursuers (which is easy for them because they are better).
It seems that seeing how the statistics and points that Napoli have and so far the opportunity to win the Serie A trophy is very close. Currently Napoli has collected 19 points and Lazio will still find it difficult. Although Napoli's Champions League schedule, which has to fight Milan, is not difficult. Interestingly, before meeting on April 13, the two will also meet on April 3, so it will be very interesting to show each other's performances as a warm-up game in the Champions League.
