If just Inter perform here like they do in Champions League, they will be in a better place! For Juve, I am pessimistic, nothing seems to be working well there..
Napoli is doing great so far in the other hand whether in CL or Serie A and I expect them to make a surprise if they can continue like that. 0 defeat after 9 rounds is impressive. For Milan, well, they are doing good also and might profit from a defeat of Napoli and Atalanta to jump in front of them.
This season is epic good and unpredictable

Inter Milan always a different team when it comes to the champions league but they're struggling in Seria A. However UEFEA have its own spirit because it's the ultimate target for every team and players play with all their strength in other to prove themselves worthy of the trophy. For Juventus, I'm still shock how they are losing to average teams in the champions league even in Seria A, the same thing occurs. Seria A clubs are performing at high level this season but Juventus is exceptional from the list.
