Roma lost ground in the race for a Champions League spot following a 2-0 defeat to Juventus at the Stadio Olimpico.
Roma were the dominant side in the first 45 minutes, but, bar a wonderful Francesco Totti volley, failed to create any clear cut chances and the Old Lady grew in stature as the match wore on.
And an increased sense of composure bore fruit in the second half when Milos Krasic put the visitors into the lead on the hour mark before Alessandro Matri put the result beyond doubt with 16 minutes of the match reamining.
Roma continued to probe but were largely restricted to efforts from distance as they attempted to preserve their unbeaten league run under caretaker coach Vincenzo Montella.
