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 is a strange match when we saw two coaches were sent off. 
Roma had a chance to score but Abraham missed it. Napoli had one finish that hits the pillar of Roma's goal. So a draw is fair for them. I understood why Mourinho was angry like that. He did not want a draw and did not want to fall further in the Scudetto race.
That draw for Napoli might cost them a lot. They were playing flawlessly so far in the league and I expected to win this match as well. Both Napoli and Milan have the same number of points (25) but Napoli is on top because of the goal difference. Juventus are still 10 points behind the leaders. What do you guys think? Will Juventus be able to get back on top of the leaderboard after still being 10 points behind?
A first draw can be a beginning of something worse for Napoli. They don't have too good substitutions to play well in whole season. Injury or fall of performance of key players can damage their performance.Juventus can participate in the Scudetto competition if Napoli or AC Milan lost 2 matches that are not impossible.
