Roma are leading 3-0 against Genoa after 45 minutes of their Serie A clash at the Stadio Olimpico.
Radja Nainggolan came close for the hosts early on, but his long-range effort was comfortably held by Mattia Perin.
Alessandro Florenzi gave Roma the lead in the 25th minute of the match when he fired a spectacular bicycle kick into the net.
Gervinho should have doubled their advantage moments later, but after bursting into the box, he fired a shot straight at the keeper.
Roma soon scored their second goal of the afternoon. Francesco Totti picked up the ball on edge of the box following another run from Gervinho and placed an effort into the bottom corner of the net.
Two minutes before the break, they scored their third. Florenzi picked up the ball on the right wing and delivered a low cross into the box that Maicon met to slot past the keeper.
