There is no reason to think that Juventus and Napoli are only playing for the title. It is true that Juventus have performed very well in the last few matches. They have been able to solve all the problems within the party. But there is no way to underestimate the AC Milan team. Milan is now second in the table. So I would say if Napoli loses the truck and drop points in several matches, then Milan and Juventus will try to win the title. Milan's performance this season is quite good. There is no way to neglect this team.
In this case what you say is true, but with Milan's current condition they are actually quite cornered in my opinion especially with their financial condition which makes this a little difficult.
Milan's current condition in the standings is still very good but on the other hand we know that they currently have a lot of gaps that make them a little insecure and even after the break is over I'm actually still quite pessimistic about how they will face this season.
