Napoli were made to work hard but they maintained their perfect start to the Serie A season with a 3-2 home win over Pisa on Monday, which took the holders clear atop the standings, Reuters reported.

Billy Gilmour netted his first goal at senior club level to give Napoli a first-half lead but M'Bala Nzola's penalty on the hour drew Pisa level.

Leonardo Spinazzola and Lorenzo Lucca's goals looked to have wrapped up the win before Lorran's late goal for the visitors made for a nervy ending, according to Reuters.
