Lewandowski and Yamal spoil Mbappé's first clasico as Barcelona beat Real Madrid 4-0

BArcelona ended Madrid's 42-match La Liga run by handing Carlo Ancelotti's side their first defeat since September 23 last year.

Lewandowski scored from a superb pass from Barcelona's latest young talent Marc Casadó in the 54th minute and headed home a second goal three minutes later to silence the Santiago Bernabeu Stadium.

They were the Polish striker's 16th and 17th goals this season, taking his best tally in the league to 14. He also hit the post.

Yamal suffered a rout in the 77th when the teenage phenom fired a shot from an angle at goalkeeper Andriy Lunin. Raphinha got involved in the claret and blue celebration when he broke free as Madrid pressed and chipped Lunin in the 84th.

Mbappé had a frustrating first match against Barcelona in the white jersey.

The French star was caught offside on several occasions by Barcelona's synchronized defense and failed to beat second-choice goalkeeper Iñaki Peña one-on-one as his side went two goals down.

Hansi Flick, meanwhile, had an unforgettable evening in the first clasico for the German coach.

Barcelona still have financial problems that cast doubt on their future, but their team has made huge strides since Flick replaced Barcelona great Xavi Hernández this summer.

Barcelona opened up a six-point lead at the top of La Liga over second-placed Madrid after 11 rounds.

“We had a difficult week with difficult matches, but we knew how to get through it. We played a great match,” said Casadó, an unknown reserve team player until Flick picked him to be his midfielder, after his impressive outing.

Casadó was one of five local players Flick had included in his starting lineup, the same 11 who had beaten Bayern Munich 4-1 in the Champions League three days before. In total, six players under the age of 22 started for Barcelona, ​​led by Yamal and 17-year-old Pau Cubarsí, and showed no signs of being intimidated by the storyline.

Yamal eclipsed Mbappé this summer when Spain beat France en route to the European Championship, and he did it again by displaying the finishing touch that Mbappé lacked.

Mbappé himself was ruled offside no less than five times in the first half hour as Barcelona pressed high up the pitch. Vinícius Júnior, author of a fascinating duel with Cubarsí, missed a golden opportunity in the 21st minute by going over the post from close range.
