Napoli stretched their Serie A lead to 11 points on Saturday after surviving a late scare against Udinese to claim a 3-2 win.
Luciano Spalletti's side were cruising to the three points after Victor Osimhen, Piotr Zielinski and Eljif Elmas gave them a three-goal lead just before the hour mark.
But quickfire strikes from Ilija Nestorovski and Lazar Samardzic left the 50,000 fans at the Stadio Maradona biting their fingernails in the final eight minutes.
Napoli held on and extended their lead at the top of the table on AC Milan and Lazio, who both play on Sunday.
Udinese stay eighth after failing to win for the seventh straight match.
