Ademola Lookman starred with a brace as Atalanta defeated Serie A leaders Napoli 3-0, marking a significant upset and their fifth consecutive league win. Lookman opened the scoring with a volley after a corner and doubled the lead with a long-range shot, both assisted by Charles De Ketelaere. Despite Napoli's attempts to respond, including a shot from Scott McTominay hitting the post, they struggled to penetrate Atalanta's robust defense. Substitute Mateo Retegui sealed the victory with a goal in stoppage time, making it Napoli's second league loss this season and their first at home. This win narrows the gap to the top of the table, with Atalanta now just three points behind Napoli. The defeat also ends Napoli's impressive unbeaten streak in Serie A, setting the stage for a challenging match against Inter Milan next week.
