Milan, Italy: Roma suffered a 1-1 stalemate on Saturday which could see them lose ground on leading trio Napoli, Juventus and Inter Milan as newcomers Benevento made history with their first ever Serie A win.
Roma took the lead when Lorenzo Pellegrini scored against his old club Sassuolo just after the half-hour in Rome only for Simone Missiroli to level after 78 minutes at the Stadio Olympico.
Eusebio di Francesco's side have a game in hand but trail leaders Napoli -- who finish the year on top after their 1-0 win against Crotone on Friday -- by nine points.
Champions Juventus could also pull further clear of the Romans when they travel to Verona later Saturday with Inter Milan, in third, hosting Lazio, in fifth.
"We were subdued, in the second half we made too many mistakes," said di Francesco. "We could have closed down the game but we didn't have the strength to do it and Sassuolo didn't give up. It was an important game to win."
Benevento made history with their first victory in the Italian top flight thanks to a Massimo Coda strike on 64 minutes which earned a 1-0 win at home against Chievo.
Roberto De Zerbi's side sit bottom of the league with four points from 19 games -- their first point coming in a dramatic 2-2 draw against Milan earlier this month.
De Zerbi's team still have a long way to go as they are 11 points off safety, but the coach insisted the victory could be a key one.
"It's an important win because it would have not been easy for me to get back to work on Tuesday trying to motivate 25 people," said De Zerbi.
