Lorenzo Insigne scored twice and set up another as Napoli thumped Fiorentina 6-0 to move third ahead of Roma who lost 3-0 to local rivals Lazio on Friday.
Insigne got the first goal in the fifth minute at the Diego Armando Maradona Stadium as Gennaro Gattuso’s side went four goals up in the first half.
Fiorentina missed chances to equalise with Napoli keeper David Ospina denying Franck Ribery before Diego Demme, Hirving Lozano and Piotr Zielinski notched three goals for the hosts in the last nine minutes before the break.
Napoli were awarded a penalty after Gaetano Castrovilli fouled Tiemoue Bakayoko. Insigne converted from the spot for his ninth goal this season.
Substitute Matteo Politano completed the rout with a minute to go.
“It looked easy but it wasn’t,” said Gattuso as Napoli moved level on points with Roma.
Atalanta missed the chance to move third, dropping points before next week’s trip to AC Milan with a goalless draw against lowly Genoa.
Gian Piero Gasperini’s side had won their first three matches of the year with a total of 12 goals scored.
Hans Hateboer rattled the post for Atalanta after 65 minutes in the best chance for the hosts who are sixth, eight points behind Milan. Genoa are 16th position, two points above the relegation zone.
