The Red Star Belgrade fans are so loud that the BBC Radio 5 live are almost shouting to be heard on the commentary.

Liverpool are entirely dominating possession and Red Star are struggling to hold it up. Milan Pavkov may leave here as a hero tonight but he needs somebody to play closer to him now.

The Reds have had 83.8% of the ball since the break

Red Star leave some space at the back for the first time in ages but Mohamed Salah can't take advantage as he runs onto Sadio Mane's pass.

Red Star threaten to break but Marko Gobeljic is bundled over by Andy Robertson.

Red Star make their second change as Goran Causic replaces the impressive Marko Marin in midfield.

Marin assisted both goals but has been quieter - as have all their attacking players - since the tactics of the game changed at the break.

Plus Marin had been booked earlier on.

Biggems: Massive shock on the cards here, especially with my Aussie counterpart Degenek playing at the back

C M: Don't know how Lallana is still on

Schemer: Mark this day as the beginning of the end for Jurgen Klopp

Hmmmmm

Sadio Mane plays in James Milner on the right and his cross is blocked by Milos Degenek, who is holding his hand in pain.

Mohamed Salah takes the corner... right into the side-netting. Poor.

James Milner crosses from the right - goalkeeper Milan Borjan catches and throws himself to the ground to eat up some seconds.

In fact Sadio Mane has swapped sides, he's on the right now so he's got a different marker anyway.

Red Star do have to make a change as Marko Gobeljic replaces Filip Stojkovic. A new opponent for Sadio Mane.

Whistles from the fans as the game continues, presumably because Red Star are down to 10 men. But that's not Liverpool's fault.

Filip Stojkovic is getting loaded onto one of those milk carts they had. He looks really frustrated at his game coming to an end. He's punching the seat in anger.

Red Star are going to have to make a change, right-back Filip Stojkovic almost seemed to do the splits and he's injured himself.

The Red Star support has been incredible all game, but you can just feel a little tint of uncertainty now.

It is going to be a hard slog for Liverpool but they have started the second half well. They need to get that first goal as quickly as possible.

Liverpool hit the crossbar, but it's not as close to a goal as it sounds. James Milner's cross is deflected, loops up into the air and hits the top of the crossbar.

Although had it dipped under the bar, Milan Borjan was rooted to the ground.

Mohamed Salah and Roberto Firmino both have the chance to join Ian Rush in joint second place in Liverpool's all-time list of European Cup/Champions League top scorers - if they can score.

Red Star fans cheer as Slavoljub Srnic slides in on Joe Gomez in the corner of the pitch near Liverpool's goal.

But now the Purples are back on the attack.

Liverpool have won just one of their last 13 Champions League matches when losing at half-time (D3 L9), in their most recent such match (2-1 at the Etihad v Manchester City).

You could probably get rid of Liverpool's half of the pitch now. A reprieve for Red Star as Adam Lallana isn't expecting Sadio Mane's pass and it's out for a goal-kick.

At half-time, you just expected at some point to see Liverpool pressing high up the pitch. That is what they are doing right now.
