Another sign of life from the visitors as Alejandro Balde is forced to concede a corner under pressure from Nico Williams.

Sergio Busquets clears the danger but is caught by Yeray Alvarez in the process. The Bilbao man appeared to step on his hand but Busquets is fine to carry on.

Nico Williams tries to outfox Alejandro Balde on the left before attempting to find Alex Berenguer inside the area, but the hosts clear the danger.

That's the closest Bilbao have come to testing the Marc-Andre ter Stegen.

And there's another chance for Kessie.

Alejandro Balde skips past Oscar de Marcos as if he wasn't there and drives a low ball into the feet of the Ivorian midfielder, who fails to direct his effort on target.

Kessie wants a corner, but the referee is having none of it.

Not for the first time this evening, Sergi Roberto is left in far too much space on the right-hand side and finds Franck Kessie, who fails to make proper contact with the cross.

What an introduction that would have been!

Here comes that change. Gavi hobbles off and Franck Kessie enters the fray.

Gavi is back on his feet but his clearly still in some discomfort.

He limps back onto the field but is limping heavily. He's going to have to come off here.

Xavi didn't like that challenge from Dani Garcia and is making his feelings known to the fourth official.

The referee eventually decides enough is enough and brandishes a yellow card in the direction of the Barcelona boss.

Gavi collides with substitute Dani Garcia and goes down in a heap.

The teenager is going to need a spot of treatment here.

Barcelona have only conceded four goals in La Liga all season - three of which came against Real Madrid last weekend.

It's a long way back for Bilbao from here.

Athletic Bilbao's evening goes from bad to worse as former Manchester United midfielder Ander Herrera is forced off with an apparent injury.

Dani Garcia comes on in his stead.

No sign of a response from the visitors just yet.

Barcelona remain in control of possession and are looking to add to their narrow lead.

VAR were checking whether Lewandowski was offside in the build-up to Dembele's strike but the goal stands.

The home fans have found their voice.

Referee Juan Martínez Munuera awards the visitors a free-kick after a coming together between Robert Lewandowski and a Bilbao defender.

Lewandowsi isn't best pleased.

Sergio Busquets tries to find Ousmane Dembele with a raking ball down the right-hand side, but it has too much pace on it for the Frenchman and goes out for a Bilbao goal-kick.

You can see why Bilbao have proved difficult to beat under Ernesto Valverde this season.

The visitors look very organised, forcing Barcelona to shift the ball from side to side in search of a pocket of space.

Inigo Martinez miscues a back-pass and Gavi almost takes full advantage - but the Barcelona man loses his footing and the ball rolls harmlessly out of play.

That was a let-off for the visitors.
