Follow LIVE coverage of the Liga match between Real Sociedad and Barcelona on Saturday, kicking off at 5pm UK time!

Xavi with a superb ball to release Alves, De la Bella is all over the place but the cross is blocked by Gonzalez. Corner.

A promising move for La Real breaks down with a poor pass inside from Prieto - shame as they had men over.

Alves was released by a marvellous long-range pass from - yes, you guessed it - Xavi.

GOAL BARCELONA! 2-0 and Pedro finishes from close range after Alves's low ball, the space created by a Messi dummy run. Superb!

Barca continuing to run rings around La Real. Barca in orange and yellow, by the way. Very Zen.

Alves is penalised for what the ref sees as a shove on De la Bella. Harsh.

Griezmann is offside as he is put through. The France U21 international was recently involved in an unsanctioned night out that resulted in lengthy bans for him and his team-mates.

While Messi's goal was a good finish the replay shows some haphazard defending in the build up. Not good enough.

More good play by Barca as Pedro wins a corner. Or not, says the ref, last touch off him.

Griezmann has a dig that goes only just wide of the far post. Barca ref-watching as they thought there was an offside.

- Sorry for the 10-minute delay – technical issues (i.e. failing internet) ruined that phase for us. Nothing of note has happened, mind. Still 1-0 Barca, Pedro also hitting the post.

MESSI SCORES! That miss was unlikely to last for long in the memory and Messi makes up for it with a cool finish with his left after Sociedad backed off him. Iniesta with the pass inside.

MESSI MISSES! First real chance as Messi is sent away down the left by Xavi but his low finish is wide of the far post!

Barca dominating the early exchanges in San Sebastian. Could be a long night for the Basques.

The first half is underway!

And goalkeeper Victor Valdes has said he will not renew his contract with the club, and will leave in 2014.

It has been an interesting week for Barcelona, with their former coach Pep Guardiola agreeing to join Bayern Munich - his successor at the Camp Nou, Tito Vilanova, thinks he has made a good decision.
