Inter Milan and Juventus are a big point ahead of the other teams with AC Milan in third position with 23 points but Juventus in 2nd position with 29 points which is a long gap. And Inter Milan who are in the first position have earned 31 points. Napoli and AC Milan are very good teams but they need to win several matches continuously to go to the first or second position while Juventus and Inter have to lose a few matches. However, Juventus have been performing much better in the Italian league this year, so I think they will show something better in the last moment and they are very likely to win the championship of the italian League
I wouldn't consider that a long gap given how young the season still is. Manchester City has been 5 points behind Arsenal for so long last season and yet won the Premier League title. 5 points really isn't all that much and they still have the games when they play against each other. But Juventus and Inter have really confirmed their performance level over quite some time now.But there are several teams that don't play as well as they normally do, like Roma, Lazio, but also Atalanta and Napoli.
Coppa Italia can also become quite interesting as all the favorites won't meet before the quarterfinals.
