Milan and Napoli got 16th win and now its really nice to see Inter, Milan and Napoli are with same number of wins and almost very very close to other points as well. A heavy competition for award from these three teams are really interesting. Adding to it, Juventus as well has shown their best performance and proved worth to be on 4th place.
We can not strike out Juventus from the game. They are moving strongly and just got two boosters from winter transfer. If three teams above keep their ups amd downs, unstable performance, Juventus will have chance to join Scudetto race in the end.
Roma will play Inter in the italian cup tonight. If they lose to Roma in this match after Milan's defeat, the motivation for Inter will gradually decrease. Afterwards, the Napoli match they will play has become very important. They will play away against Napoli. If Napoli win they will be the leader so they will prepare very well against Inter.
I wish Roma will beat Inter because it will be good for them and for Serie A. As you said, if Inter fail again, even in Coppa Italia, they might fall into a crisis like Napoli after they lost their long win streak. Milan, Napoli and Juventus can take advantage of it and make Scudetto competition more tightly and exciting.
