Lorenzo Insigne, Chucky Lozano, Diego Demme and Andrea Petagna allowed Napoli to make short work of 10-man Crotone, leaping into joint third place.
The Partenopei were still missing Victor Osimhen and rested Dries Mertens ahead of a crucial Europa League game, so Andrea Petagna stepped in. Crotone were rock bottom and missed Luca Cigarini, Andrea Rispoli, Luca Siligardi and Emmanuel Riviere.
There was heavy rain and strong winds in Calabria, but unlike Udinese-Atalanta, the game was able to start.
Petagna curled wide, though he also went down in the box on 14 minutes, but the referee saw he ran into Marrone rather than the other way round.
Petagna threatened again on a smart Lorenzo Insigne slide-rule pass, stinging Alex Cordaz’s gloves at the near post.
Nwankwo Simy also nodded over, but Napoli took the lead with a moment of sheer quality. Piotr Zielinski got away with a nutmeg, spread the play for Insigne, who cut inside for a trademark right-foot curler into the far top corner.
Crotone continued to keep good possession and David Ospina had to make a sliding tackle on Pedro Pereira outside the penalty area.
Vulic came on for not fully fit Ahmad Benali and within a minute had forced a tricky save out of Ospina with his volley.
Chucky Lozano sprinted through the centre on the stroke of half-time and was bundled over by Cuomo not far outside the area, but Insigne’s free kick was straight into the wall.
The second half started even worse for Crotone, because Petriccione went in very high over the ball on Diego Demme and caught him on the calf. After viewing it again on VAR, the referee opted for a straight red.
Napoli doubled their lead by making the most of very slack defending, as Insigne’s cross found Lozano in so much space that he had time to chest it down and half-volley in from six yards.
Junior Messias tried an audacious lob from midfield when spotting Ospina off his line, but the game was otherwise entirely comfortable for the Partenopei.
They made it 3-0 with Diego Demme’s angled drive, set up for him by a Dries Mertens no-look pass after Tiemoue Bakayoko had won it back in midfield.
Even Petagna got in on the act during stoppages with a powerful finish that bent back Cordaz’s glove on another Mertens assist.
The result allows Napoli to leapfrog both Roma and Sassuolo into third place, level with Juventus, all with a docked point.
