Victor Osimhen and Khvicha Kvaratskhelia helped Napoli get a 2-1 home win against lowly Cagliari in Serie A on Saturday.
Napoli now moves provisionally up to fourth in the standings.
The African Footballer of the Year broke the deadlock for the hosts in the 69th minute after Cagliari keeper Simone Scuffet deflected his header on to the post and saw the ball bounce into the net as a result.
Cagliari forward Leonardo Pavoletti equalized three minutes later from close range, but Kvaratskhelia restored the lead for Napoli after Osimhen superbly controlled the ball to tee him up 15 minutes from fulltime.
Champions Napoli moved up two places to fourth on 27 points from 16 games, 11 points behind leaders Inter Milan, who visit mid-table Lazio on Sunday. Cagliari are 16th with 13 points.
