Napoli thumped their hosts, Leece, 4-0 on Saturday at the Stadio Via del Mare, with goals from Victor Osimhen among them.
The Nigerian player, who had to start the game on the bench, came in for Giovanni Simeone at halftime and immediately made an impact.
Six minutes into the second half, the forward scored to double Napoli’s lead.
At the far post, the 24-year-old nodded in Kvicha Kvaratskhelia’s exquisitely floating cross.
When Napoli were awarded a penalty late in the game, Osimhen threw up the opportunity to score his team’s second goal and instead transferred the ball to Matteo Politano.
The Serie A champs’ top scorer has scored five goals in seven league games so far this season.
Rudi Garcia’s squad also got goals from Leo Ostigard and Gianluca Gaetano.
