Barcelona thrashed runaway leaders Real Madrid in a statement win at the Bernabeu in a dominant display.

Real Madrid, who had won the previous five Clasicos, are nine points clear of Sevilla with nine matches to go after the humiliating defeat, with third-placed Barcelona a further three behind with a game in hand.

Pierre-Emerick Aubameyang scored twice on his Clasico debut and set up Ferran Torres on the night.

Aubameyang and Ronald Araujo headed in crosses from a rejuvenated Ousmane Dembele before the break and Aubayemang then flicked the ball into the path of Torres for their third to the bewilderment of the home crowd.

Ex-Arsenal striker Aubayemang chipped in a fourth from a Torres pass to claim his 10th goal in nine games for the Blaugrana in all competitions.

Barca are now unbeaten in 12 games and Xavi said: "I don't know if we can win the title, we can't rule out anything. Maybe we're a bit late, but this is a very big win for us.

"We were much better than Real Madrid. We played almost as a home team in the the ground. It's a day to enjoy, not only as a Barca manager but also a fan.

"We could easily have scored five or six. We changed our negative dynamic of losing the last few Clasicos."

Barca midfielder Sergio Busquets added: "If we still have a small chance to make a run for the title, we will fight until the end. It's very difficult but in football anything can happen. We are Barca."

Real boss Carlo Ancelotti took responsibility for the heavy loss, saying "it's my fault" - but urging his team to "forget it and move on".

They were missing the injured Karim Benzema, who has been the outstanding player in La Liga this season with 22 goals and 11 assists.

It would have been even worse for Real if not for keeper Thibaut Courtois, who made six saves in the game.
