Napoli extended their Serie A winning streak to nine games as first-half goals from Victor Osimhen and Eljif Elmas secured a 2-1 comeback victory at second-placed Atalanta on Saturday that saw them stretch their lead at the top to eight points.
Atalanta's Ademola Lookman opened the scoring after 19 minutes when he converted a penalty after a handball by Osimhen.
Napoli's 23-year-old Nigerian international made amends four minutes later when he headed the ball into the net off a cross from Piotr Zielinski.
In the 35th minute Elmas put the visitors in front after taking a pass from Osimhen inside the box, with his effort flying into the net via a slight deflection off Atalanta's Hans Hateboers.
Napoli have 35 points after 13 games ahead of Atalanta on 27 and AC Milan with 26 before they host Spezia later on Saturday.
