The Partenopei fell behind but won comfortably in the Europa League clash
Napoli had to come from behind away to Legia Warsaw in the Europa League on Thursday, and while they trailed it looked as though their European season might have been drawing to an end.
But Mahir Emiral's early goal was as good as it got for the Polish side, before the Partenopei roared back in the second half.
Piotr Zielinski levelled with an early penalty after the break, and Dries Mertens converted one of his own with a quarter of an hour to play, giving the Italians the lead.
Hirving Lozano grabbed their fourth before Adam Ounas put the cherry on top of the icing on the cake.
Napoli, with the win, secured top spot for the time being, leapfrogging Legia.
