Barcelona rivals Real Madrid 5-2 in a wild Spanish Super Cup Clasico final in Saudi Arabia on Sunday to win the first trophy of the Hansi Flick era.
Kylian Mbappe put Madrid ahead, but the Barcelona giants hit five in reply before their goalkeeper Wojciech Szczesny was sent off in the second half.
Madrid were hoping to avenge their 4-0 home defeat to Barcelona in October's LaLiga Clasico but were instead left battered and bruised by their arch-rivals in Jeddah.
After Mbappe's opener, Lamine Yamal leveled and Robert Lewandowski put Barcelona ahead from the penalty spot, Raphinha got a brace and Alejandro Balde was also on target.
Rodrygo Goes pulled one back for Madrid with a free-kick but they were unable to capitalize on their numerical advantage in a humiliating loss to the European champions.
“It's really nice, it's been a season since we won a cup. It's always special and, moreover, in the Clasico against Real Madrid,” Barcelona defender Jules Kounde told Movistar.
“We had a lot of calm and patience, knowing that if we executed the plan we would win.
“I'm very proud and happy with the team… right after the red card, we came together and said we had to suffer, sit back, but we had a big advantage and that can't go away. “
'Poor defending' cost Real Madrid the game
Real Madrid coach Carlo Ancelotti said that his team's poor defense was the main reason for the big defeat.
“We defended badly and that cost us the game – they found their goals very easily,” Ancelotti told Movistar.
“We're sad, like all our fans, it's disappointing, and we don't have to hide that… we have to look forward, there's nothing else we can do.”
Both coaches chose to keep the same teams they started in the semi-finals.
Yamal issued an early warning to Madrid with a curling effort from the right which saw Thibaut Courtois make a fine save.
The Belgian goalkeeper also made a strong stop to keep out Raphinha's header after Brazilian Lucas Vazquez easily avoided it.
Despite Barcelona's opening salvo, it was Real Madrid who took the lead in the fifth minute with Mbappe's brilliant goal on the counter.
The French striker, repeatedly fouled by the offside flag in the league defeat to the Catalans, broke free on the halfway line after Vinicius won the ball back and, from after bursting into the area, he passed Szczesny.
Barcelona bounce back from a goal down
It took a stunning individual goal from 17-year-old Yamal to level the scores, with the Spanish winger cutting in from the right before smacking home a low finish inside the near post in style similar to former Barca great Lionel Messi, with. it is often compared.
Barcelona kept pushing and moved ahead through Lewandowski's penalty after Eduardo Camavinga's late arrival and careless head-butting of Gavi.
Raphinha soon added Barcelona's third with a header from Kounde's cross from deep, and they grabbed their fourth before half-time on the break.
Yamal and Raphinha combined and the latter slipped to Balde, who went past Courtois.
Barcelona followed suit after the break and Raphinha completed the fifth with a neat dribble and finish after Marc Casado was played in.
The Catalans were reduced to 10 men when Mbappe went in at the other end, rounding goalkeeper Szczesny, who brought him down outside the area and after a VAR review was dismissed .
Rodrygo, who had hit the post earlier, slotted home the free-kick past Szczesny substitute Inaki Pena.
Bellingham and Mbappe leave Real questions for Madrid
Mbappe teed up Jude Bellingham brilliantly, but the England international was denied by Kounde's superb challenge in stoppage time.
The French striker also came close to scoring again in a fine individual display, but Pena blocked his effort.
“He was the best (Madrid player),” said Ancelotti, noting the improvement after Mbappe's debut at the club, following his switch from Paris Saint-Germain.
Barcelona brought on midfielder Dani Olmo for his first appearance since being signed to play for the club on a temporary basis, a controversial issue that overshadowed the semi-finals earlier this week.
However, their five-star display offered several other talking points as Barca won a record-extending 15th Spanish Super Cup.
