Tenacious Torino held Roma to a 1-1 draw at home to stop the leaders' all-time record of consecutive wins at the start of a Serie A season to 10.
Roma travelled to the Olympic Stadium yesterday with hopes of restoring their five-point lead over title rivals Napoli and Juventus, who closed the gap to two points with wins over Parma and Catania respectively on Saturday.
However, Alessio Cerci's second half toe-poke was enough to secure a share of the spoils, and bring Torino some welcome headlines, when it levelled Kevin Strootman's first-half opener for the visitors.
Roma, still unbeaten and having conceded only their second goal in 11 games, remain top on 31 points with a three-point lead on both Napoli and champions Juventus with Inter and Verona a further six points off the pace.
With Juventus hosting Napoli next weekend, Roma will be looking to capitalise on slip-ups by either side when they host newly-promoted Sassuolo.
Roma coach Rudi Garcia, meanwhile, had only praise for his players.
"I liked the fact that for the whole 90 minutes we went out and played to win," said the Frenchman.
"Even when we were sitting level, we kept on pressing for the winner. But that's football. You can't always win, and away from home a 1-1 draw is not a negative result."
Roma have become the team to watch so far this season following the appointment of Garcia, who is still without Ivorian striker Gervinho and captain Francesco Totti due to their respective injuries.
But while in with the chance of claiming an 11th consecutive win to match the best ever start to a season by any team, namely Tottenham in the 1960-61 season, in the top five European leagues, Torino had other ideas.
Dutch midfielder Strootman gave Roma a 28th-minute lead when he beat Daniele Padelli in the hosts' goal with a curling left-foot strike.
