Kubo netted against his old side and Barrenetxea netted the second

Barcelona are 14 points clear at the top of La Liga, after Real Madrid slipped up at the Reale Arena against a Real Sociedad destined for the Champions League.

Dani Carvajal was sent off to compound a difficult night for Carlo Ancelotti's side.

Takefuso Kubo broke the deadlock early in the second half, before Carvajal was shown a second booking.

Barrenetxea netted the second in at Thibaut Courtois' near post. Game over. League over.
