They've 'add' a 'mare!

Barça were left with egg on their faces on Sunday after mistakenly boasting of an 11-point LaLiga lead over Atlético Madrid on social media.

El Barça se lía y no sabe cuántos puntos le saca al Atlético

Barcelona were left red-faced by another social media gaffe on Sunday night, failing to do the maths before publishing an infographic on the points advantage they currently enjoy in the LaLiga title race.

In a post comparing Barça's lead with those of the teams topping other major leagues in Europe, the Catalan club accidentally bumped up their nine-point cushion over second-placed Atlético Madrid to an even more healthy 11.

With 30 games played in LaLiga so far this season, Luis Enrique's men have accrued a total of 76 points, with Atlético behind them on 67.

Barcelona have since deleted the offending graphic.

The clanger comes fresh on the back of a post last month in which Los Azulgranas' official Twitter account referred to Camp Nou chief Josep Maria Bartomeu as "president Bartolomé".
