Napoli and Palermo served up a thrilling 3-3 draw that keeps up both sides' inconsistent start to the Serie A season.

Rafael Benitez's side went ahead inside the opening two minutes through Kalidou Koulibaly when the French defender rose highest to head home Jose Callejon's cross after Palermo failed to deal with an early corner.

Napoli doubled their lead on nine minutes through striker Duvan Zapata's powerful finish from Marek Hamsik's pass.

Palermo pulled one back seven minutes later when Andrea Belotti converted Edgar Barreto's cross and then dramatically levelled the tie through Argentine midfielder Franco Vazquez on 24 minutes.

On the stroke of half time Callejon restored Napoli's lead with a smart finish from the edge of the Palermo box, but Palermo once again bounced back as Belotti's second of the night just after the hour mark rescued a point for the away side.
