Real Madrid 0–4 Barcelona: To make matters worse, Lamine Yamal and Raphinha strike after Robert Lewandowski scored twice.

Barcelona blasted Real Madrid away to increase their lead over the fierce rivals to six points at the top of La Liga, with Robert Lewandowski scoring twice and Lamine Yamal and Raphinha also scoring.

It was a startling night for the hosts in the Spanish capital as Kylian Mbappe, playing in his first-ever El Clasico, had attempts in both half disallowed for offside.

Jude Bellingham and Mbappe wasted chances to put Real Madrid back in the game after Lewandowski missed two gilt-edged chances to score what would have been a historic hat-trick.

Before Raphina chipped Andriy Lunin late to add insult to injury on a humiliating night for the home team, Lewandowski was also involved in Barcelona's third goal, which saw Yamal crash home to score his first El Clasico goal.

Marc Casado's incredible ball in the 54th minute gave Barcelona striker Lewandowski the lead, and three minutes later, he headed home a second goal to quiet the Santiago Bernabeu.

The Poland striker's league-best total now stands at 14, with the goals being his 16th and 17th overall this season. He struck the post as well.

In the 77th minute, the adolescent sensation rifled a shot from an angle over Lunin, giving Yamal the victory.

As Madrid pressed ahead, Raphinha burst free and chipped Lunin in the 84th minute, joining in the burgundy-and-blue celebration.

Wearing a white shirt, Mbappe's first game against Barcelona was frustrating.

Barcelona's synchronised back four caught the France star offside several times, and with his team trailing by two goals, he was unable to defeat second-choice custodian Inaki Pena one-on-one.

Meanwhile, the German coach Hansi Flick had a memorable night in the inaugural Clasico. After 11 rounds of games, Barcelona had a six-point lead over second-place Madrid at the top of La Liga.
