Napoli moved within three points of Serie A leaders Juventus, after coming from behind to defeat Genoa 2-1 at a rain-drenched Marassi.
Christian Kouamé headed home from a pinpoint Rômulo cross to open the scoring for Il Grifone in the 20th minute, after Lorenzo Insigne had struck the post for the visitors within the first ten minutes of the game.
The match was suspended close to the hour mark due to adverse weather conditions, but when it resumed, the visitors were on top and drew level through substitute Fabián Ruiz in the 62nd minute, before Davide Biraschi turned the ball into his own net to give Carlo Ancelotti's side a late winner.
