Lazio were fourth at the start of the day but were unable to move within six points of the lead as they suffered a 4-0 defeat at the hands of Catania. The visitors had no answer as two Alejandro Gómez strikes and Francesco Lodi’s penalty made it 3-0 at the break, before Pablo Barrientos rounded off the scoring in the second half.
Meanwhile, Napoli were unable to cut the deficit to three points as they failed to win at home in the league for the first time this season. Edinson Cavani’s sixth-minute goal appeared to have earned the points for the Partenopei against Torino, before Gianluca Sansone struck in added time.
Fiorentina moved ahead of Lazio, into fourth, as goals from Gonzalo Rodríguez, Stevan Jovetić, Luca Toni and Juan Guillermo Cuadrado gave them a 4-1 triumph against Cagliari, while AS Roma lie sixth following a 4-1 defeat of Palermo.
Elsewhere, Pescara defeated Parma 2-0 and Sampdoria’s winless Serie A streak now stands at eight games following their 2-1 home loss to Atalanta.
