Lovely link-up play between Lionel Messi and Martin Braithwaite which sets up a chance but Osasuna just about scramble it clear before Philippe Coutinho can pounce.

Confident start to the half by the visitors as Marc-Andre ter Stegen is forced into save before Barca attack through Jordi Alba.

And Koeman has indeed made a change at the start of the half.

As if Osasuna's afternoon could not be any harder, Sergio Busquets is on for Pedri.

And off we go again. Three, four, five? Or will Osasuna launch a fightback?

The teams are heading back out for the second half. Barca have a trip to Hungary to face Ferencvaros in the Champions League on Wednesday. Expect changes this half.

Having started the day 14th, Barca are now up seventh in the table as it stands. There's more goals in this. I've just seen a replay of Griezmann's volley. Absolutely gorgeous.

More like it from Barca.

The best 45 minutes of Barcelona's domestic season?

It's got to be up there.

Oh my. Brilliant from Marc-Andre ter Stegen to keep out Oier Sanjurjo's header, the Barca keeper then keeping out the follow-up before Osasuna finally get the ball in the back of the net.

The flag goes up. It won't count.

It's all turned a bit scrappy since the goal which will suit Osasuna who will be keen to get to half-time without conceding again. Sergino Dest concedes a silly free-kick which gives the visitors a chance of launching an attack.

Martin Braithwaite outshining Lionel Messi.

That's 2020 in a nutshell.

So far so good for Barca. Will they finish the job off? Osasuna look dangerous on the break but the hosts are controlling play and carving out chances.

Two goals in the Champions League in midweek. Another today. Martin Braithwaite is making it hard for Ronald Koeman to leave him out.

Lovely stuff by Lionel Messi who tries to set up Martin Braithwaite but it's scrambled behind for a corner. Ronald Koeman has his hands in his pockets. His players are struggling to unlock Osasuna's defence.

Juan Cruz is on for Osasuna. Jonny has taken in the stand so maybe not as serious an injury as first feared?

Barca continue to dominate but the visitors are holding firm.

Jony pulls up with an injury and immediately sits down.

Play continues, Barcelona don't want to put the ball out of play.

Eventually play is stopped and Osasuna are going to be forced into an early change.

Barca haven't kept a clean sheet in La Liga since 1 October and there's a reminder that they remain vulnerable at the back when Ante Budimir volleys over from close range.

It wouldn't have counted had it gone in. Offside.

They're getting closer and closer with every move.

This time it's Antoine Griezmann who goes close from about 15 yards.

Osasuna are just about hanging on.
