Roma deserved a draw with their unrestrained pressure at the end of the match and their great desire, while Napoli was just trying to keep the winning score technically, and his majesty football often punishes for this. This does not detract from the fact that Napoli is Inter's main competitor for the Scudetto, although the team seems to have lost a player like Kvaratskhelia, around whom Antonio Conte wanted to form the team, but as we can see, they are still coping without the Georgian player.
There is not much pressure that Roma might put on when facing Napoli and I see Roma tending to play safe to get a draw. But that did not work for Napoli in targeting full points because Napoli actually had a little difficulty in finishing the chances to score. On the other hand, the result of the match did not have much influence because Inter Milan themselves as their strong challengers also got a draw when facing AC Milan so this did not give a big loss to Napoli or Inter Milan themselves in the match.
