Roma is a Renowned team in Serie A. At the beginning of this season, the performance of this team was very weak. However, I have seen the performance of Roma players in the last few matches. At the moment, Roma's performance is somewhat stable. So Napoli team could not get 3 points in this match.
However, since Napoli is fighting for the title, getting 3 points in this match was very important for Napoli. But Napoli failed to get 3 points. If Napoli's performance is so irregular, they will not be able to keep the top position of the table.
Inter Milan also failed to win against AC Milan in their last match. If Inter Milan could win this match, they would have been able to regain the top position of the table in the next few weeks.
Ranieri has been able to change Roma for the better, and in the match against Napoli they played very well, considering that it was a match against the league leader. I remember Ranieri saying that he knew he would be sacked, but now it seems that everything has changed for the better and Roma are playing much better. Inter also lost points in the match against Milan, so for Napoli this tour was not something bad, although Inter have a game in hand and a better goal difference, so they can still displace Napoli.
