With AS Roma condition this season, Napoli should be able to take advantage of the condition to steal points because this victory will return them to the top of the Serie A standings. The 13th match is the capital that Conte needs to maximize, he managed to bring Napoli in his first season very well so AS Roma must be defeated badly. For Conte there is no option to share points at this time.
Ranieri first match as Roma coach did not go well after the defeat to Napoli, but I think in that match there was a significant improvement in Roma performance and also the game although they could not avoid defeat, Roma who are currently managed by Ranieri I think have a brighter prospect to rise than currently coached by Ivan Jurig previously, Facing Napoli who are in good form of course requires a team to have better squad depth, but Roma is still able to keep up with Napoli's game in the match even though their squad is not better than Napoli currently has, defeat is still a defeat but behind it all, of course Ranieri must be able to gain experience to improve his squad later when facing the next match in Serie A or in the UEL.
Claudio Ranieri's records rightly vindicates him as good manager that's capable of doing exploits with any team so I don't think it'll be nice to judge him with his first result as an AS Roma boss. Their game against Napoli yesterday was a difficult one for them which I think was expected knowing how impressive the league leaders have been this season. I believe Ranieri will improve the team's winning ratio in coming games in the Italian Serie A and in their European games.
