Jonathan de Guzman scored a hat-trick as Napoli moved into the top half of Europa League Group I with a comfortable 3-0 home victory over Young Boys.
The Holland international notched a sensational first goal from wide on the left wing to give the Italians the advantage heading into half-time and he doubled up shortly after the hour mark.
The team from Bern offered little in the way of resistance and a lack of concentration allowed De Guzman to claim the match-ball after scoring an easy third goal in the last 10 minutes.
Napoli join Sparta Prague on nine points ahead of the final two rounds while Young Boys, with six points, slip into third place above only pointless Slovan Bratislava.
It was one-way traffic at the Stadio San Paolo as Napoli used Young Boys for shooting practice.
Lorenzo Insigne could have scored twice in the first 15 minutes - his second shot was brilliantly saved by Yvon Mvogo - and De Guzman soon drilled over the crossbar when well-placed to fire home.
Insigne tried to curl one in shortly before Gokhan Inler sent Mvogo sprawling with a drilled shot from distance.
When Mvogo tipped Insigne's audacious dipping effort over the bar it looked like Young Boys had done enough to survive until the interval.
They did not expect De Guzman to score such an incredible opener, however.
Standing in a good crossing position on the left the former Swansea midfielder instead picked out the far corner and looped the ball home from 30 yards with remarkable accuracy.
De Guzman went after his second when play resumed and Mvogo did well to smother a drilled shot.
Weaker efforts from Insigne and Duvan Zapata followed before De Guzman converted his brace in the 65th minute.
The finish was not quite as majestic but he got the job done as he slipped Zapata's pass beyond Mvogo.
Jose Callejon emerged from the bench to further concern Mvogo and his first act was to drill a rocket into the Swiss goalkeeper's gloves.
De Guzman upgraded his brace to a hat-trick in the 83rd minute.
A poor clearance from the bewildered Mvogo landed at the Dutchman's feet and, after taking a touch to beat the last man, he poked the ball home from six yards.
