Barca are taking nothing shots from range now. There's no creativity from them, no sense of urgency.

Change for Sociedad. Pablo Marin comes on for Ander Barrenetxea.

The Nou Camp is silent.

Barca are creating a bit more but nothing truly clear-cut just yet.

Jordi Alba has a go from range but his shot deflects behind for a corner.

Should be 2-0!

Takefusa Kubo play in a fantastic ball to the back post where Alexander Sorloth meets it, two yards out. But somehow the forward heads it wide when it would have been easier to score. Criminal!

Great play from Takefusa Kubo who twists and turns and wins a foul as he's clattered down by Jordi Alba.

Real Sociedad now have a wide free-kick in a dangerous area.

First hint of time wasting from Real Sociedad. Jeers ring out as the visitors take an age to take a goal kick.

Xavi has seen enough.

Raphinha and Franck Kessie come off to applause. They're replaced by Ansu Fati and Ferran Torres.

And immediately Sociedad's two subs combine with Gorosabel setting up Takefusa who pierces a shot straight at Marc-Andre ter Stegen.

Double change for Real Socieded.

Takefusa Kubo and Andoni Gorosabel come on for skipper Asier Illarramendi and Mohamed-Ali Cho.

Barcelona chance as Ousmane Dembele cuts on to his left foot but the forward mishits a shot well wide of the near post.

Real Sociedad's first attack since the restart. Alexander Sorloth picks up the ball before spraying it out wide to Mikel Merino.

But the forward's first-time shot skids beyond the far post.

Robin Le Normand is OK to continue. That was very cheeky from Robert Lewandowski. Another referee on another day...

Barcelona win a corner kick, but nothing comes of it as Robert Lewandowski elbows Robin Le Normand in the back as it's delivered.

In fact the forward gets a yellow card for the foul.

Real Sociedad look so comfortable. They're bullying the champions in their own backyard.

Early chance for Barcelona after a sloppy clearance from Real Sociedad keeper Alex Remiro but Robert Lewandowski is swarmed by defenders in the penalty area and can't get a shot away.

Barcelona have made a change at the break. Marcos Alonso comes on for Jules Kounde.

With Alonso, Jordi Alba and Alejandro Balde, Barca now have three left-backs on the pitch.

Off we go.
