Maurizio Sari's team preserved its perfect start to the season with a comprehensive 4-1 win over Lazio, to join Juventus at the top of the table, on 15 points.

Napoli's superior goal difference has it above the defending champion.

With 19 strikes from five matches, Partenopei Gli Azzurri are averaging almost four per game. 

Today the scoring load was spread out among the team as goals from Kalidou Koulibaly, Jose Callejon, Dries Mertens and Jorginho put an abrupt end to Lazio's own unbeaten start to the season.
