I can't think of many occasions Bruno Guimaraes has ever signalled to come off.

But the Newcastle United captain has not looked right since suffering an ankle issue.

It is rather telling that he has had to come off just minutes before half-time.

Newcastle supporters are on their feet to applaud him off the field and chant his name. The Brazilian is limping badly as he makes his way down the tunnel.

A chance on the stroke of half-time as Jorrel Hato's well-struck effort is kept out by Jay Gorter.

It is goalless at the break, but Gorter has been busy.

Bruno Guimarães cannot continue as he continues to hobble and he is replaced by Lewis Miley just before half-time. The Newcastle fans are on their feet to applaud him.

Bruno Guimares has asked to come off for the third time. He is hobbling severely.

Now then, there's a VAR check for a penalty here against Timothy Weah. Jeremie Frimpong's cross rolls down Weah's arm.

Anyway, no penalty. Too high up the arm, apparently.

The lead didn't last long!

Slavia Prague equalise straightaway - and it comes from another corner.

Near post again, flicked on again and this time it hits Barcelona striker Robert Lewandowski and goes in! Own goal.

Jeremie Frimpong is fouled but he quickly gets to his feet and sends a lofty ball to the back post.

Ryan Gravenberch goes past Leonardo Balerdi on the edge of the box and he's brought down. Chance here.

PSV are forced into a change just before the break as Anass Salah-Eddine is injured. He is replaced by Armando Obispo.

There have been a smattering of chants for former owner Roman Abramovich chants after Pafos hit the post but seems a vocal minority thus far.

Barcelona have turned this around - and that's a lovely strike from Fermin Lopez.

A superb, curling effort from 20 yards out finds the bottom corner to give the Spanish forward his second of the night.

A great move again from Liverpool for that Salah chance. They are getting numbers into the box and are not afraid to leave two on two at the back at the other end.

Italian side Atalanta lead Athletic Club and it's striker Gianluca Scamacca with the finish in the 16th minute.

Chelsea want a goal before the break and Moisés Caicedo lets fly with a powerful one from distance but Jay Gorter dives to push the effort away.

The Blues keep up the attack, however.

Liverpool need to make this dominance count. Surely Marseille won't be this poor going forward in the second half.

Really good chance for Bayern from a corner but Raphael Guerreiro heads over.

The defender is on the receiving end of a few words from Harry Kane after that. The England man was just behind him and felt it should have been left for him,

You certainly would have backed Kane to bury that from about five yards out.

Again the Marseille fans are trying to roar the team on, as soon as they win the ball back you can hear the crowd starting to go because if they pass the ball forward quicker, they can get in behind the defence but they're allowing Liverpool to get back into shape.

That's another decent chance for Liverpool. It's been a good half for Arne Slot's side. They look organised and seem comfortable enough but again, it's a performance that is just lacking that bit of class in the final third. At least for now it is...

Florian Wirtz frees Jeremie Frimpong wide right. He's got time to pick out the near post run of Mo Salah but the Egyptian thighs it over the bar.

That's a chance.
