Napoli moved alongside Juventus at the top of the Serie A table with a routine 2-0 win over Catania on Saturday, while Torino drew with Sampdoria.
The damage was done before half-time, with Marek Hamsik opening the scoring after 31 minutes and Paolo Cannavaro adding another 13 minutes later.
Napoli are unbeaten in seven league matches and are now level on 49 points with Juve, who travel to Chievo on Sunday.
Catania remain seventh and with two points to make up on the European places.
In Saturday's other match, Torino stretched their unbeaten run to seven matches but did little to set pulses racing in a goalless draw with Sampdoria.
The hosts impressed in a 2-2 draw at Inter Milan last time out but little of that fight was on display here, as they were cancelled out by a Samp side also on a high following last week's 6-0 win over Pescara.
