Expect thrills, spills and plenty of goals as Fiorentina host Roma in a battle for European qualification.
These clubs are old rivals and go head-to-head at the Stadio Franchi. It kicks off at 19.45 UK time (18.45 GMT), click here for a match preview.
The Viola are in fourth place and just one point behind Milan in the final Champions League spot, so they are desperate to continue their march up the table.
Stefan Savic is suspended in defence, while Facundo Roncaglia, Michele Camporese and Giuseppe Rossi are injured, so Marvin Compper steps in.
Stevan Jovetic is fit to start with Adem Ljajic and Juan Cuadrado completing the 4-3-3 system.
Roma have had a middling campaign, but are still in the race for Europe and have reached the Coppa Italia Final.
They beat Fiorentina twice already this season in Serie A at the Olimpico and in the Coppa Italia in Florence, so provide a tough test for their former Coach Vincenzo Montella.
Maarten Stekelenburg is still sidelined by injury, but Daniele De Rossi is fit to start and Mattia Destro returns from suspension.
Pablo Daniel Osvaldo is facing his old club and, according to transfer gossip, possibly his next teammates too.
Last season Fiorentina won this game 3-0, but the Giallorossi ended the match with nine men after Juan, Fernando Gago and Bojan Krkic saw red.
Goals are to be expected, as both teams have been on target at least once in all but one of their last 14 games.
