Barcelona will be baffled they're not ahead at this point. They've kept Atleti mostly quiet but their final touch hasn't been strong enough.

Atletico Madrid skipper Koke is a lucky boy.

He hacks at the right leg of Lamine Yamal despite already being on a yellow card.

The referee surely won't accept any more mistimed tackles from him.

Liverpool cannot get out. PSG's press is brilliant and it's almost like they are playing keep-ball when they get possession.

That is a great save again from Giorgi Mamardashvili. He has to be completely aware of the through ball and he is on top of Désiré Doué before he can lift his head up.

Another big save from Giorgi Mamardashvili to keep the score as it is.

It looked sure to be 2-0 as Desire Doue got himself free in space six-yards out.

But the Georgian keeper closed him down and made the save with his legs.

The Atletico Madrid fans, housed high up in the Gods at Camp Nou, are doing their best to encourage their side.

Diego Simeone scratches his head on the touchline. His side could do with half-time to reset.

PSG have had 72% possession in this half so far.

Around 10 minutes to go until the break.

This game has become one-way traffic since a frantic opening.

Atletico Madrid have not had a shot since the 11th minute.

Lamine Yamal shows glorious close control to turn and weave in and out of three Atleti defenders, but his goal-bound shot is blocked.

Barcelona recycle possession and Gerard Martin tries his luck from the edge of the box, but his shot flashes narrowly wide of the bottom corner.

He has got so much pace, Desire Doue. Doue has got away from Alexis Mac Allister and Mac Allister knew it.

It was a challenge Mac Allister had to make.

Khvicha Kvaratskhelia hit it first time and took everyone by surprise. That was a big paw from Giorgi Mamardashvili and it was finding the bottom corner.

Khvicha Kvaratskhelia forces compatriot Giorgi Mamardashvili into a good save on the stretch.

Liverpool will be desperate not to concede again.

Koke trips Dani Olmo and is booked.

Pedri has also picked up a yellow card.

After receiving treatment a few moments ago, Atletico Madrid defender David Hancko is replaced by Marc Pubill.

It's a lazy challenge for me, no need to make it. Just cover the run down the line.

Marcus Rashford again!

Dani Olmo's clipped diagonal cross is just too high for Robert Lewandowski, but Rashford does brilliantly to reach it on the stretch.

His effort is goalward from a tight angle, but unfortunately for him Juan Musso is able to block and gather.

Another booking the visitors.

This time it's Alexis Mac Allister who is shown a yellow card for a late challenge on Desire Doue. The Argentine was nowhere near the ball.

Almost half an hour on the clock.

Forget about shots on target, Liverpool are yet to register an attempt.

A promising attack from Liverpool but Ryan Gravenberch can't get the ball out of his feet properly and PSG pounce.

Joe Gomez makes the challenge to prevent the counter attack but he's shown a yellow card for his efforts.

A spell of Barcelona possession results in Joules Kounde curling in a dangerous ball towards Robert Lewandowski, but Robin Le Normand manages to head clear with the Polish striker lurking.

Barcelona have settled after an end-to-end start to this match and are looking to find gaps in an organised Atletico defence.
