Roma lead Fiorentina 1-0 at half time courtesy of Radja Nainggolan's 26th-minute goal.
Gervinho had an early opportunity to fire the Gillorossi ahead after meeting a cross inside the box, but he failed to find the target after working some space inside the area.
Nainggolan did give the visitors a first-half lead on 26 minutes, however, when he reacted quickly to get in front of Neto and fired a close-range shot into the back of the net.
Francesco Totti almost doubled his side's advantage shortly before the interval, but he shot the ball wide of the target after pouncing on a rebound on the edge of the box.
