Claudio Marchisio scored in the 44th minute to take the Bianconeri to within six points of Serie A leaders Inter Milan, who host Roma tomorrow night.

Napoli are still searching for their first win in eight Serie A matches and remain stuck in mid-table .

Two goals from Mauro Zarate earlier helped Lazio to a comfortable 2-0 victory over Bologna, their first win at the Stadio Olimpico since December.

Zarate fired Lazio into the lead in the 36th minute with a powerful free-kick and then doubled his side's advantage nine minutes from time.

The victory pushed Lazio into seventh spot, while Bologna remain just a point above the relegation zone.
