Rudi Garcia's Roma side trail Juventus by nine points in Serie A but have a game in hand after their match against Parma last week was postponed due to a flooded pitch.
With 17 games left in the Serie A season, Roma cannot afford to drop further behind the dual-reigning champions from Turin and must beat Lazio on Sunday if they are to remain in the hunt for the Scudetto.
If Garcia's men are to win against Lazio, who are on a five-game unbeaten run in Italy's top tier, Gervinho will surely produce a top performance as the Ivory Coast forward is in top form at the moment.
In Roma's past five games in all competitions, Gervinho has scored four goals and set up another three, playing up front on the left as part of Garcia's preferred 4-3-3 formation.
Gervinho scored twice in Roma's 3-2 win over Napoli in their Coppa Italia semi-final first leg on Wednesday, while the 26-year-old former Arsenal attacker struck once and set up Ljajic for Roma's opening goal in a 3-1 triumph away to Hellas Verona in their last league fixture.
If Lazio continue their recent dominance in the Derby della Capitale, third-placed Napoli could draw within three points of Roma, although Rafael Benitez's men are struggling this month.
