However, the visitors took the lead in the 14th minute when Josef Husbauer fired in from the edge of the box after Napoli had failed to clear a corner.

Midway through the first half Napoli were awarded a penalty after Nhamoinesu Costa handled Jose Callejon's effort, as the Spaniard followed up Marek Hamsik's shot that had come back off the bar.

Gonzalo Higuain, who had missed a penalty in his last match, stepped up and made no mistake with a confident finish into the bottom corner past David Bicik.

Six minutes after the break Napoli scored their second goal of the evening through Dries Mertens, who slotted home Higuain's low delivery from close range.

The hosts continued to press for another goal and Mertens had an effort ruled out for a handball, before Kalidou Koulibaly headed wide.

Callejon then worked an opportunity for himself as he found some space on the edge of the box before seeing a low shot saved by the keeper at his near post.

With nine minutes left to play, Mertens made sure of the points as he scored his side's third goal of the evening when he tricked his way past two defenders and fired a strike into the bottom corner.
