The hosts began on the front foot as Jose Callejon latched on to Mertens's ball to strike a ball goalward, but the effort flew wide.

Duvan Zapata then opened the scoring in the 19th minute by tucking the ball into the bottom corner past goalkeeper Antonio Mirante.

Napoli continued to push forward and create chances, while all Parma could offer in the early stages was an Antonio Cassano effort from 35 yards that posed little danger.

The Partenopei went on to double their lead on the half-hour mark when Massimo Gobbi conceded a penalty in the Parma box.

Mertens make no mistake from the spot, smashing the ball into the top-right corner for his side's second goal.
