Napoli will soon lose every UEFA competitions spots and might risk not playing any international game next year by the end of the season. Their results aren't satisfying, only two points out of 9 in the last three matches and things don't seem to be promising when we find them taking 3 goals from Atalanta without scoring any.
Later today, we will see if Juventus will be as unlucky as Napoli or they will recover. Milan game isn't that easy too against Fiorentina. I expect Milan to win and Juventus to draw.
Napoli situation is bad and they can lose their position to Fiorentina or Lazio but the league is on going and Napoli can complete this season with a spot to Conference League. It is not what they ambitiously aimed at when the season started months ago but now they can not hope for a higher position than that.
At least AC Milan can help Napoli this week but there will be more weeks and matches so Napoli must fight by themselves and can not rely other clubs in Serie A to beat Atalanta, Fiorentina and Lazio for Napoli benefit.
