With the three points all but wrapped up, Xavi decides to make a triple change.

Robert Lewandowski, Pedri and Jules Kounde make way for Ferran Torres, Ansu Fati and former Chelsea man Marcos Alonso.

Oihan Sancet replaces the stricken Dani Garcia.

Oscar de Marcos also comes off for fellow full-back Inigo Lekue.

Dani Garcia, who replaced Ander Herrera in the first half, has picked up an injury of his own and is going to have to come off.

Ousmane Dembele isn't settling for a goal and two assists, drilling a low, long-range effort into Unai Simon's arms as he looks to add to his early opener.

The visitors win a free-kick in a central position, around 35 yards from goal.

Marc-Andre ter Stegen and Jules Kounde appear to get in each other's way as they look to clear the danger and the ball rolls out for a Bilbao throw.

How did that not go in?

Ousmane Dembele feeds Sergi Roberto, whose cross takes a deflection and trickles towards the far post towards Pedri. The 19-year-old almost diverts Dani Garcia's attempted clearance into the net for number four, but the ball strikes the post and bounces clear.

A flowing Barcelona move ends with Sergi Roberto sending his attempted cross behind for another Bilbao goal-kick.

The 30-year-old is frustrated with himself there. He knows he should have done better.

Pedri tries to pick out the run of Alejandro Balde on the left but it goes behind for a goal-kick.

Barcelona are slowly getting back into their stride.

Credit to the visitors - they've certainly made a lively start and don't appear to have abandoned hopes of an unlikely revival.

They need an early goal to stand any chance of mounting a comeback here.

Barcelona switch off for a second, allowing Niko Williams to take a touch before fizzing a low ball into the six-yard area from the right flank.

It's too close to Marc-Andre ter Stegen, though. Another easy save for the Barca keeper.

And away we go!

The players are back on the pitch. Neither side has made any further changes.

One towering header and two clinical finishes.

Barcelona are cruising.

Plain sailing for the home side, who lead through goals from Ousmane Dembele, Sergi Roberto and Robert Lewandowski.

Nico Williams, who has come to life in the last few minutes, wriggles past Ousmane Dembele on the left but his low cross is cleared to safety.

That'll be the final action of a one-sided first half.

Alex Berenguer tries to catch Marc-Andre ter Stegen out with a curling effort towards the far corner but it's an easy stop for the German goalkeeper.

There will be five minutes of additional time at the end of the first half.

The visitors are enjoying their best spell of the game as we approach the end of the first half - but it's surely too little too late...
