Barcelona hammered 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 Mbappé put Madrid ahead but a dominant Barcelona hit five in response before their goalkeeper Wojciech Szczesny was sent off in the second half.

Madrid were hoping to avenge their 4-0 home defeat by Barcelona in October's La Liga Clasico but instead were left battered and bruised by their arch-rivals in Jeddah.

After Mbappé's opener, Lamine Yamal levelled and Robert Lewandowski sent Barcelona ahead from the penalty spot, with Raphinha bagging a brace and Alejandro Balde also on target.

Rodrygo Goes pulled one back for Madrid with a free-kick but they could not capitalise further on their numerical advantage in a humiliating defeat for the European champions.

"It's really nice, it had been a season since we won a trophy, it's always special and on top of that in a Clasico against Real Madrid," Barcelona defender Jules Kounde said. "We had a lot of calm and patience, knowing that if we applied the plan we would win."

"I'm very proud and happy with the team," he added. "Right after the red card, we got together and said we were going to have to suffer, sit back, but we had a big advantage and this can't escape us."

Real Madrid coach Carlo Ancelotti said his team's poor defending was the main reason for the heavy defeat.

"We defended badly and that cost us the game – they found their goals quite easily," Ancelotti said. "We're sad, like all our fans, it's disappointing and we don't have to hide that – we have to look forwards, there's nothing else we can do."

Both coaches opted to maintain the same line-ups they started with in the semi-finals.

Yamal issued Madrid an early warning with a curling effort from the right which forced Thibaut Courtois into a fine save.

The Belgian goalkeeper also produced a strong stop to keep a Raphinha header at bay after the Brazilian evaded Lucas Vázquez with ease.

Despite Barcelona's opening salvo it was Real Madrid who took the lead in the fifth minute with Mbappé's brilliant goal on the counter-attack.

The French forward, frustrated numerous times by the offside flag in the league defeat by the Catalans, broke loose on the halfway line after Vinicius won the ball back and, after bursting into the area, clipped past Szczesny.

It took a stunning individual goal from 17-year-old Yamal to level the scoreline, with the Spanish winger cutting in from the right before stroking home a low finish inside the near post in a similar style to former Barca great Lionel Messi, to whom he is often compared. (AFP)
