Barcelona condemn fans for 'violent and disdainful acts' against Ronald Koeman after Real Madrid loss

Barcelona on Sunday condemned the "violent and disdainful acts" faced by their coach Ronald Koeman when he left Camp Nou stadium after a 2-1 defeat by arch-rivals Real Madrid earlier that day.

Videos on social media showed people surrounding Koeman's car and blocking it from moving as the Dutchman tried to exit the stadium after Barcelona suffered their fourth straight defeat in Clasicos.

As Koeman drove away, the video showed several spit marks on his driver’s-side window after supporters vented their anger with the result.

The club quickly issued a statement to condemn the scenes witnessed in the aftermath of the result - the fifth game out of nine this season that Barcelona have failed to win and their second defeat in three matches.

"FC Barcelona publicly condemns the violent and disdainful acts that our manager experienced when leaving the Camp Nou," the Catalan club said on Twitter.

"The club will take security and disciplinary measures so that such unfortunate events do not happen again."

Barcelona are ninth in La Liga, with 15 points from nine matches, six points behind leaders Real Sociedad who have played an additional game.

Koeman has come under scrutiny in the wake of the team's mediocre results, leading to speculation over his future at the club.

Goals from David Alaba and Lucas Vazquez saw Real Madrid secure victory and move six points clear of Barcelona to remain just one point behind La Liga pacesetters Sociedad.

Alaba registered his first goal since joining Real over the summer when he fired past Marc-Andre ter Stegen just after the half-hour mark.

Vazquez doubled the advantage for Carlo Ancelotti's men in the third minute of stoppage time with a close-range finish, before substitute Sergio Aguero opened his Barca account by pulling a goal back with almost the last kick of the contest.

It made it three defeats from three Clasicos as Barca boss for Koeman.
