Great free-kick. The wall is big, though. What is the goalie thinking? He has hit it well and with pace. It is just what Liverpool need - that away goal.

Trent Alexander-Arnold
What a free-kick! And what a moment for the 18-year-old Trent Alexander-Arnold.
The right-back, on his European debut, curls the ball superbly over the wall and into the far corner, well out of reach of the goalkeeper.
Fine strike and a crucial away goal for Jurgen Klopp's men.

Some of the movement has been good, but when they get into the final third there is little quality from either side.
We are waiting for that little bit of quality. There are enough players out there to show it.

Jurgen Klopp does a bit of repair work as he tucks in a bit of upturned turf on the edge of the pitch close to his technical area.
The Liverpool boss will be reasonably happy with what he has seen so far. The hosts have had more of the ball, but how long can they keep up their intensity?
Hoffenheim 0-0 Liverpool
The hosts have had 60% of the possession but just one shot on target so far.
The home crowd, vociferous at the start, have quietened down a bit. Ermin Bicakcic recognises this and waves his arms up and down to encourage them to keep up their support.

You know it's a hot night when bare chested men populate the home terraces with their banners and flags bouncing up and down non-stop. They're having the night of their lives compared to the Liverpool fans who are rather subdued camped in the corner of the stadium.

It is a good ball in but where is Alberto Moreno? He is in no man's land. He has to get back in and support Lovren.

Half a chance for the hosts as a cross is sent to the far post where Pavel Kaderabek hasn't been picked up but he lashes well over.
That was Alberto Moreno's man. The Liverpool full-back is not doing a great deal to change Mark Lawrenson's mind about him so far...
Hoffenheim 0-0 Liverpool
Hoffenheim's baby-faced manager Julian Nagelsmann strides to the edge of his technical area to shout some instructions at his players. He appears to be urging them to calm down a bit. The hosts have been lively, but their eagerness to get forward quickly has left them exposed to the counter a couple of times.

Breaking transfer news away from this game and Liverpool's rivals Everton have agreed a deal to sign Swansea's Gylfi Sigurdsson for a fee believed to be around £45m.
Matt VP: This Hoffenheim coach appears to be auditioning for the Arsenal job the way this team play.
Chris Duckworth: Penalty save from Mignolet just papers over @LFC, external defensive cracks

Kevin Vogt gives the ball away cheaply and Liverpool try to release Sadio Mane but, fortunately for Vogt, his Hoffenheim team-mates snuff out the danger.
The hosts are enjoying plenty of the possession but Liverpool are lively on the counter.

Defending for both sides has been questionable so far. The way things are looking we could easily have another 3-3 on our hands.
Liverpool win a corner but Trent Alexander-Arnold's delivery fails to beat the first man.
Hoffenheim 0-0 Liverpool
Now Liverpool should be ahead!
A terrible mistake by Hoffenheim skipper Kevin Vogt allows the Reds to break on the counter through Mohamed Salah. He's one-on-one but has got almost half the pitch to travel and by the time he gets to the box he has Vogt on him again and ends up stabbing his shot wide.
Sho Rahman: That is an absolutely horrific penalty. No wonder why Leicester let him go
Javel Bleach: Well if it's that easy, #Liverpool, external should get 3 or 4 penos in the game. #Mignolet, external didn't dive. Studied the taker?

Normally Mignolet is a bit of villain. But he guessed right and it was a comfortable save. Some people would say it is not a penalty so that is justice for them.
Hoffenheim 0-0 Liverpool
Poor penalty!
Andrej Kramaric steps up to take the spot kick but his it straight down the middle and it's an easy bat away for Simon Mignolet.
Jurgen Klopp flashes a relieved smile at his bench as he applauds Mignolet's save. That was a big chance for the hosts to take the lead.

Dejan Lovren has been a mistake waiting to happen and so it proves as he gives away a penalty, clumsily challenging Serge Gnabry in the box.
Penalty to the hosts...
