Most likely Juventus and AC Milan will wait for the moment from the 4 clubs, expecting all four to experience defeat or make mistakes in several important matches and later it will be utilized by Juventus and AC Milan, but even so the result of the Juventus versus AC Milan match indicates that the match really expects a draw from these two big clubs, even so Atalanta, Inter Milan, Fiorentina and Lazio, are still considered tough but of these 4 clubs the one that stands out is Atalanta compared to other big clubs, because consistently in every match Atalanta, Fiorentina, Lazio always get a good win so that's why Napoli's current competitor is not Inter Milan but these 3 clubs who are likely to win the Serie A title this season.
I personally might see that all the teams in the top 5 currently have almost the same strength. And actually it will be quite difficult to expect any defeat from these top 5 teams unless they face each other and beat each other or get a draw.
Juventus' position, which is currently ranked 6th, is only 3 points different from all the teams ranked 2 to 4, so Juventus' opportunity to return to a better ranking is still quite easy. But for AC Milan it looks like they will need a longer time to return to the top 4 rankings. because currently AC Milan has very different points from the teams ranked 2 to 4. AC Milan has 19 points and that means 9 points different from Lazio and the others.
But AS Roma's condition is much worse. Because they are still fighting at middle ranking.
