Partido de vuelta de los octavos de final de la Liga de Campeones disputado sin público en el Camp Nou.
Barcelona are into the quarterfinals of the Champions League after a 3-1 win over Napoli at Camp Nou on Saturday delivered a 4-2 aggregate win.
Quique Setien's side will now face Bayern Munich, who knocked out Chelsea, in the last eight in Lisbon next Friday.
Lionel Messi was on top form in the first half against Napoli as Barca won the tie in the opening 45 minutes.
Clement Lenglet headed in the opener before Messi took over, scoring, having a goal ruled out for offside and winning a penalty which was converted by Luis Suarez.
Napoli got one back thanks to a Lorenzo Insigne penalty and will look back on what could have been after making a fast start.
Dries Mertens hit the woodwork early on as Napoli roared out of the blocks but the pattern changed when Lenglet headed home Ivan Rakitic's corner to open the scoring.
That goal woke Barca from their slumber and a fine team move was capped by some Messi's brilliance to make it 2-0. Messi beat two mean before slipping to the floor, but managed to pick himself up, take a brilliant touch and curl home.
Messi thought he had another when he controlled Frenkie de Jont's fine cross and finished but VAR ruled he'd been aided by the use of a hand.
The Argentine was in the thick of the action now and he was central to the move which did end up with Barça's third goal of the night. He was booted by Kalidou Koulibaly after nipping in front of the Napoli defender and, after a lengthy review and the use of the pitch side monitor, a penalty was awarded.
Suarez struck home from 12 yards to seemingly wrap up the win.
But Napoli were given a lifeline just before the break when Ivan Rakitic fouled Mertens in the area. Captain Lorenzo Insigne brought the Italians back into the game.
Barca relaxed after the break and Napoli pushed but they never really threatened Marc-Andre ter Stegen's goal.
Milik had a late goal ruled out for offside and Barca will head to Portugal next week.
