Barcelona beat Napoli 3-1 on Tuesday and advanced to the Champions League quarterfinals 4-2 all around after a nervous second half.
Fermin Lopez and Joao Cancelo gave Xavi Hernandez's team the early lead, but the Catalans began to perspire after Amir Rrahmani equalised.
After surviving a 1-1 draw in the first leg of the round of 16, Italian champions Napoli ended up losing by Robert Lewandowski's close-range strike.
Barcelona, the four-time champions, have not advanced past the round of eight in the competition since 2020, and they accomplished this feat without the injured midfield three of Pedri, Gavi, and Frenkie de Jong.
After announcing in January that he would be leaving at the end of the season, coach Xavi Hernandez's squad went on a nine-game winning streak.
During a terrible season, Barcelona was given a relief on a night when they beat Napoli, thanks in large part to the performances of teenage stars Lamine Yamal and Pau Cubarsi.
Xavi insisted that those watching make their temporary Olympic Stadium Montjuic hill in the city into a pressure cooker, and they carefully followed. The crowd of almost 50,000 people was the highest for the club this season.
Napoli under Francesco Calzona wilted away as the Spanish champions stormed out of the starting blocks.
Electric Yamal, a 16-year-old winger, started the game by making good advances down the right and looping over.
Lopez had the best opportunities, and after 15 minutes, the 20-year-old scored on his third goal.
Lopez tucked the ball home after Cancelo feed Raphinha, who cut the ball back into the box.
Although he might not have Pedri's metronomic accuracy, the midfield player has energy and an unquenchable thirst for goals.
After two minutes, the visitors were left shocked as the Catalans increased their lead by two goals. Yamal started the counterattack by breaking away in the attacking half.
The Brazilian hit the post during the winger's match in Raphinha, but Cancelo was there to roll in the rebound.
When Matteo Politano in through the right, Ronald Araujo played him onside as Napoli fought their way back in.
The winger from Italy squared the ball for Rrahmani, who finished neatly to give Napoli a point again.
Shortly after, Napoli was on track for a draw the score, but Barcelona goalkeeper Marc-Andre ter Stegen produced an incredible save by blocking Giovanni Di Lorenzo's header.
With Barcelona pushed back into their half after a careless clearing of the ball, the Italians had a great start to the second half.
Xavi moved encourage the midfield and give his team a boost by substituting Sergi Roberto and Oriol Romeu for Andreas Christensen and Lopez.
Alex Meret made stops from Raphinha and Lewandowski before Yamal hit from close range, but his shot was offside.
Jesper Lindstrom, a Danish winger, missed a close opportunity to score for Napoli before Lewandowski, assisted by Ilkay Gundogan and Sergi Roberto, won the match.
Barcelona's second-half jitters revealed that they are far from their past glory, but they still have enough skills, especially in Yamal, Raphinha, and Cancelo, to trouble any possible opponent in the quarterfinals.
