Real Madrid's 42-game unbeaten La Liga run comes to a bitter end as Barcelona wins Clasico 4-0

Barcelona's Robert Lewandowski scored a quick-fire second-half double to set the leaders on course for a 4-0 thrashing of Real Madrid in a stunning Clasico victory in La Liga on Saturday.

Real were in control of the game from early on but became frustrated as they wasted several clear chances before Polish striker Lewandowski silenced the Bernabeu crowd with a two-goal blitz after quick counter attacks in the 54th and 56th minutes.

As Real tried to get back into the contest, Barca killed them off with two more goals on the counter as 17-year-old Lamine Yamal became the youngest Clasico scorer in the 77th minute and captain Raphinha wrapped up the win in the 84th.

Barca stretched their lead at the top with 30 points, six above Real who saw their 42-game unbeaten La Liga run come to a bitter end after 13 months, leaving them one tantalizing positive result away from equaling the Catalans' league record of 43.

"I'm delighted to be working at Barcelona and to live in Barcelona. It's a fantastic job, I'm very happy... We have played a fantastic game and I am so proud," Barcelona manager Hansi Flick, who has been living an outstanding start at the helm of the Catalonia giants with 10 wins from 11 La Liga games, told a press conference.

"The defensive effort was key. We have trained a lot how to defend with a high line and on how we want to press on the ball. It's also important not to leave spaces when you play Real Madrid because they have incredible players.

"I think we are doing well. We are sticking to our idea and right now we are fluid and we want to move forward."

Ancelotti rues missed chances

Real Madrid manager Carlo Ancelotti lamented his side's missed opportunities in their stunning 4-0 home defeat.

"It was an evenly played match, until they scored their first goal. We played with intensity in the first half but lacked a bit of accuracy. We had chances to take the lead but they scored two goals, which sapped our energy. That's when another game started," Ancelotti told a press conference.

"We are hurt, it's a tough moment, but I want to thank the fans for their support. We don't have to throw everything away, because there is nothing to throw away," added a downhearted Ancelotti.

Ancelotti said he thinks Real Madrid deserved better and that he didn't believe the result told the true story of the match, but acknowledged that his team paid the price for missing so many chances.

"The result doesn't reflect what happened on the pitch. We couldn't take the lead and they went ahead and took it. The game, until the first goal, was very even and we had more chances," Ancelotti said, before commenting on Mbappe's lackluster performance, being caught offside nine times.

"It was known that Barca use a high defence and we barely took advantage of it. (Mbappe) had chances and sometimes was offside, but he had three or four chances where he needed to be more accurate..."
