Andrea Petagna came off the bench to give Napoli victory along with Fabian Ruiz, but Genoa were furious at Goran Pandev’s harshly-disallowed goal.

The Partenopei had to use Lorenzo Insigne as a makeshift centre-forward, with Victor Osimhen suspended, Dries Mertens, Piotr Zielinski, Diego Demme and Faouzi Ghoulam injured. Genoa were still smarting after a 4-0 opening defeat to Inter, but still without many of the new signings made late into the transfer window, including ex-Napoli defender Nikola Maksimovic.
