Marc Casado praised Barcelona’s daring high line following a resounding 4-0 Clasico victory against Real Madrid in LaLiga.

The win put an end to Madrid’s aspirations of a record unbeaten run in the league as they were unable to equal Barcelona’s streak of 43 games without loss between 2017 and 2018.

Instead, the Santiago Bernabeu witnessed a finessed Hansi Flick offside trap as the hosts were caught offside a whopping eight times in the first half, representing their joint most on record (since 2003-04) in a single LaLiga match, equalling their tally against Celta Vigo in March 2013. 

They were ultimately caught out 12 times in total, and Barcelona midfielder Casado, who bagged an assist, was enamoured by his side's defensive display.

"It's incredible, to have the b**** to have the defensive line this high," he said in the mixed zone.

"We've been doing it all season, the defensive work of this team is spectacular. It's incredible and at the moment it's working for us."

His delight was unsurprising. Barcelona managed to nullify the Real Madrid threat with forward Kylian Mbappe caught offside eight times through the duration of the match.

It is the most by any player in a single game in Europe's top five leagues since Karim Benzema against Eibar in November 2018.

Barcelona were firing at the other end too, as Robert Lewandowski bagged a brace before Lamine Yamal and Raphinha doubled their margin of victory late on.

It means Barcelona now have 10 wins in 11 games so far this season under Flick, leaving them six points clear at the top of LaLiga.

Goalkeeper Inaki Pena, who came through the ranks at Barcelona, has been impressed by the turnaround in form since the coach's off-season arrival.

"I'm super happy now, I am a proper Culer. We suffered a lot towards the end of last season, it was a tough time," he told Barca's official media channels.

"Flick came in and just told us how much we had to believe in ourselves, on a personal level and on a collective level."

Both Casado and Pena came through La Masia, which remains a key source of talent for the Catalan giants.

"We know that this club always brings out very good players from the academy, I don't know how it happens but it always comes out. The work at La Masia is spectacular and that's why we arrive so prepared for the elite," Casado added.
