it is a good result for Ac Milan though to temporarily share the first spot with Napoli and Atalanta with the same amount of points, but the situation of Juventus keeps getting worse, and they probably won't even end up in the top 6 if they keep things like this with no change, a lot of fans want Allegri to be out asap, and it might the right thing to do but not financially.
This is clear as I imagined and AC Milan's victory over Juventus is something that should have happened, because AC Milan's players have the motivation to win the game and they have it now so AC Milan's position in the standings has started to improve, although in the near future it will there is another change because some of the teams in the top rankings still haven't played their 9th match.
