A Gonzalo Higuain brace helped Maurizio Sarri's Napoli to a 5-0 victory over Lazio in their Serie A clash on Sunday.

The Argentinian striker opened his account for the night after 14 minutes, seeing off a Wesley Hoedt challenge before firing in from 20 yards.

Brazilian midfielder Allan made it 2-0 with a 35th-minute strike from a Lorenzo Insigne through-ball.

Insigne then got himself on the scoresheet just after the restart as he turned Dusan Basta before shooting past Federico Marchetti.

Higuain added his second of the night soon after, bringing his tally for the season to four goals in four games.

After 65 minutes Higuain made way for Manolo Gabbiadini, who made his mark on the game in the 79th minute by converting Napoli's fifth after being set up by Allan.

The Azzuri's 5-0 win moves them up to 11th position in the Serie A table, one place behind Stefano Pioli's Lazio side in 10th.
