First corner for La Real.

Jordi Alba goes close for Barca - and then the offside flag goes up. He runs onto a long ball, cuts inside a couple of defenders and draws a save from Alex Remiro. Wouldn't have counted.

A good first touch by Martin Braithwaite to find a bit of space but then his cross is overhit.

Lionel Messi shoots over the bar from 25 yards then.

Real Sociedad's Adnan Januzaj gets annoyed by the pressure he's getting from Oscar Mingueza and leaves an arm in the Barca defender's face.

The Belgian gets a yellow card but it could have been worse.

Barcelona have had five shots to Real's one - but most of them have been blocked.

Barcelona are dominating but they are struggling to fashion proper chances. Their final ball has been lacking.

Lionel Messi is given the ball on the halfway line, he goes for a run but can't get past the last defender.

He's not having a great season by his standards, five La Liga goals in 11 games. No assists.

Barcelona have the first corner of the game, Ronald Araujo gets his head to it but can't get an effort on goal.

Portu shoots wide for La Real after Ronald Araujo had blocked an initial effort.

Two summer signings combine for Barca and go close. Pedri plays it out to Sergino Dest on the right and races into the box before getting on the end of a Dest cross which he heads just wide.

A clever cushioned side-footed volley from Antoine Griezmann, but it goes just wide of the far post.

Both of today's managers played the last time Barcelona did not win this fixture at the Nou Camp.

Ronald Koeman and Imanol Alguacil played in a 1-1 draw on 9 April 1995.

Sorry for anyone checking in for David Silva, he's injured at the moment.

Martin Braithwaite is offside as he gets the ball on the left. This is his sixth start in seven games - not bad for what appeared to be a stop-gap signing last year.

You know the drill if you want to have your say on this game, tweet in.

Barcelona's first attack but Lionel Messi's cross is blocked. Now Pedri finds Messi, whose shot is blocked.

Barcelona have won their last 22 La Liga games against Real Sociedad at the Nou Camp.

Real Sociedad's last win over Barcelona was in April 2016. Barca have won six and drawn two since then.

And awaaaaay we go.

Real Sociedad have actually drawn their past six games in all competitions.

They are unbeaten in 10 games since the end of October.

Barcelona boss Ronald Koeman: “We have to have more confidence in ourselves and have the ball to create danger and goalscoring opportunities.

"Real Sociedad's success is in large part down to the coach's system. They have players who without the ball are excellent. They take risks playing from the back but we have things that can make it difficult for them.

"In general we can't be happy with some of the results we have had in La Liga. We have lost games we should not have even though in the last game the attitude and performance was very good."
