Philippe Coutinho accelerates into the penalty box but David Edwards times his challenge just right to clear the danger.

Liverpool make another change - Daniel Sturridge is on, Roberto Firmino is off.

In the second half, Liverpool have had 83.2% possession and Wolves have made 31 passes, compared to the Reds' 154. Remarkable, given the scoreline.

The coaching committee of Wolves are having a chat now, saying "what can we do to alleviate this pressure".

A save for Wolves keeper Harry Burgoyne! At last!

Liverpool's first attempt on target comes from sub Philippe Coutinho, who has a go from just outside the area with his right foot. 

Burgoyne is then sent in to action again, when Coutinho pumps forward to an on-rushing Alberto Moreno, but it's overcooked and goes out of play.

Roberto Firmino has a go from about six-yards out and it's blocked by two Wolves bodies, and then Ben Woodburn tries to loop the ball back in for another attempt but it's cleared again.

Woodburn is having a much better game in the second half. 

Ovie Ejaria tries to get a shot in but it's blocked by Wolves defender Kortney Hause on the edge of the area.

Liverpool are really piling on the pressure now. The visitors are at full-stretch at the back. 

Sympathy, I think it would be fair to say, is currently in short supply.

The ball keeps coming back at Wolves now, the visitors are beginning to give it away too easily, too often.

Ben Woodburn bursts forward and finds Roberto Firmino in the box. But as he cuts the ball across...there's no-one there to pick it up. 

The ball starts to bobble around in the Wolves area. It's scrappy but Kortney Hause clears the danger.

From one side of the box to the other, Ben Woodburn loops the ball over and finds Alberto Moreno, but the Liverpool man gets forced back under pressure.

Wolves counter again and gather pace in attack.

Georginio Wijnaldum receives a yellow and concedes a free-kick for a heavy tackle on Wolves' playmaker Helder Costa.

Costa has been a real handful all afternoon.

As much as Liverpool were booed at the end of the first half, there's been nothing but applause since this second half started.

Richard Stearman got a yellow in the first half and now his centre-back partner Korney Hause is also booked for bringing down Divock Origi on the right flank. Origi was clear, with open turf in front of him.  

The resulting free-kick comes in but it bounces off the red shirt of Ragnar Klavan and out for a goal kick. 

Substitution made, we are back under way at Anfield.

I think you can probably guess, but that's Liverpool's heatmap on the left, with Wolves on the right.

The hosts have had almost all of the ball in the middle third but rarely threatened in the Wolves area, with the visitors countering and happy to hit the flanks.

How long has Jurgen Klopp been here, 15 months? I'd say this is his lowest ebb of his reign.

The nature of the two goals they've conceded today are abject, absolutely hopeless.
