Two goals in each half helped Napoli see off Albanian champions Egnatia in their third pre-season friendly, and first against international opponents in Castel di Sangro.
Kvichva Kvaratskhelia netted in his maiden appearance of the summer following a trademark burst of pace and an angled finish.
Matteo Politano's left-footed strike then put the Azzurri in the driving seat before the break.
Antonio Conte changed the entire line-up except Alessandro Buongiorno at the start of the second half and within seven minutes of the restart Giovanni Simeone made it 3-0.
Cyril Ngonge completed the scoreline midway through the half with a delightful dinked effort.
The Azzurri will next be in action at the Stadio Patini on Wednesday when Brest will be in town.
