I haven't come to a conclusion about Napoli yet because anything is always possible, but I'm worried about how disappointed the fans will feel after this team loss points and fails in the end.
As they are 8 points ahead of second-placed AC Milan. Napoli is in very good form right now. If they can maintain this form, they will not lose 8 points in the next matches. And if Napoli does not lose points, no other team can close the points gap with Napoli. We still don't know how the teams will perform after the World Cup. But if Napoli doesn't lose form badly, and is able to put in some consistent performances, they are guaranteed to win the title.
Napoli's upcoming matches in Serie A will have a level of quality of opponents that are more difficult than what Milan will face. Juventus and Inter have recently seen their form improve with successive wins in Serie A, one mistake from Napoli will give the way for Milan to further destabilize Napoli's position in the standings.
Can Milan defend their Serie A title with only half a season remaining?
