Title hopefuls Napoli were thumped 3-0 at the Stadio Luigi Ferraris after coach Carlo Ancelotti tinkered with the team, dropping captain Marek Hamsik and forward Jose Callejon.
Gregoire Defrel scored two first-half goals to put Sampdoria in command and, although Napoli improved after the break, Quagliarella added a third with an outrageous flick in the 75th minute.
A low cross was sent into the area and the 35-year-old forward, at the near post, diverted it into the net with the back of his heel
