Napoli and Roma are two team that have strong defense so far in Serie A so this draw in my opinion is fair enough for both of them. Previously Roma were doubtful for point in that match, but Mourinho and his players' determination to steal point from Napoli went smoothly and currently Roma have managed to occupy the fourth position in the standing with 16 point.
That's right, Napoli is a team that has a strong defense this season, they have only conceded 3 goals in Serie A. It's certainly very good to be champions this season. I still can't say much about Milan. Even though I'm a Milan fan, but looking at last season, I'm still a little doubtful whether AC Milan can be consistent and surpass Napoli to become champions this season or they are down after winter transfer.
