Double change for Liverpool.

Divock Origi replaces Georginio Wijnaldum, while Alex Oxlade-Chamberlain enters the fray for Mo Salah.

Ooof!

Roberto Firmino's fierce shot from the edge of the box catches Bjorn Engels square on the forehead.

That's going to hurt in the morning!

There’s still a long way to go, I don’t know if it might be interesting for Aston Villa to put El Mohamady on one wing and Taylor on the other wing to stop Liverpool full-backs coming forward, because the two wide men at the moment are not helping defensively a great deal.

Another fabulous chance for Liverpool, and what a save this is by Tom Heaton!

Trent Alexander-Arnold's cross towards the far post is met by Sadio Mane, but the forward's header strikes Heaton's shoulder and bounces clear.

Former Villa keeper Peter Schmeichel would have been proud of that one!

Obviously all eyes are on the Liverpool and Manchester City games and I am looking forward to seeing how it pans out.

I still think there will be a change in results there. I think Liverpool and Manchester City will win. It's just a matter of time.

City are currently trailing at home to Southampton.

Mohamed Salah blazes over from a good position inside the box.

Things just aren't going Liverpool's way.

What an opportunity for Liverpool, but Jordan Henderson makes a mess of it.

Tyrone Mings misses his challenge near the half-way line and Henderson charges towards the penalty area. The midfielder has time and space to pick out one of Sadio Mane or Mo Salah, but his tame pass finds neither and Villa clear their lines.

Adam Lallana tries to feed Sadio Mane but the midfielder's through-ball trickles straight through to Tom Heaton.

It's been all Liverpool since the restart but Villa's slender lead remains intact.

Two routine saves in quick succession from Tom Heaton.

Georginio Wijnaldum shoots straight at the Villa goalkeeper from the edge of the area, before Sadio Mane's low effort is easily gathered by the 33-year-old custodian.

The visitors have made a lively start to the second half and go close to en equaliser within minutes of the restart.

Sadio Mane's cross finds Roberto Firmino inside the area, who fails to direct his effort on target. Villa clear the resulting corner.

We're back under way!

Liverpool manager Jurgen Klopp has ruled out fielding different teams in two competitions in two countries - possibly on the same day - to solve the club's Carabao Cup quarter-final issue.

The Reds were drawn to play Aston Villa in the last eight in the week commencing 16 December, when they are in Qatar for the Fifa Club World Cup.

Read the full story here.

Thirteen of the 16 goals conceded by Dean Smith's side this season have come after half-time.

Still all to play for at Villa Park.

Villa deserve their narrow lead at the break.

Liverpool with plenty of work to do in the second half.

Liverpool win a free-kick in the final minute of added-on time. Trent Alexander-Arnold swings in the cross but Matt Targett heads clear.

That should be the last action of the half...

John McGinn tries a through-ball to Trezeguet, who is adjudged to be in an offside position.

There will be three added minutes at the end of the first half.

Mohamed Salah fires over the bar after latching on to Sadio Mane's ball into the Villa box.

It was a poor finish from the Egyptian, who had done well to turn his marker inside the area.

That is three VAR checks now at Villa Park and each has been as welcome as a Birmingham City title win by the home crowd.

They slammed it when it was checking the opening goal, did the same when it ruled out a Liverpool equaliser and have just completed the hat-trick while it ruled over a possible penalty for Sadio Mane (not given).

Meanwhile, Jurgen Klopp is prowling his technical area, hands in pockets and visibly frustrated. His side are in a battle against a side who a well up for the fight.

Liverpool are ending the first half strongly here.

Sadio Mane tries to slip the ball through to Mohamed Salah who feels he is being held by Bjorn Engels in the area.

Goal-kick given.

Oh dear.

Sadio Mane goes down in the area under Frederic Guilbert's challenge and is shown a yellow card for diving.

Contact was minimal but VAR are still having a look at it. That decision was never going to get overturned, though.
