Good work from Conor Gallagher. He dribbles away with it on the left, cuts inside of Jordan Henderson and earns a foul.

West Brom push a few players up and will launch it long.

Callum Robinson gives one for Karlan Grant to chase. He does but Alisson waits for him to exert all his energy before tapping it left to Andy Robertson.

Any more goals to come? The half has flown by.

A good omen.

Poor Karlan Grant has about five Liverpool players around him as he tries to hold the ball up on the left, waiting for Grady Diangana to catch up.

His teammate does catch up eventually, but Georginio Wijnaldum has already won it back.

Bit adventurous from Karlan Grant, West Brom's number 29...

Mohamed Salah picks up a clearance on the edge of the West Brom box, takes one touch and hits a wicked strike. It flies just over the bar.

How is it only 1-0?

Abhishek: This is so cruel. Allison deserves to sit down and have a breather. Somebody give that man a chair!

Kev: West Brom are already losing...why are they still playing so defensive? This isn’t football. It’s surrendering.

Shak: 11 men camped in their box. Welcome Big Sam. Give me Leeds and Bielsa-ball any day!

A rare attack for West Brom. Those Liverpool fans sat in the Kop are seeing the ball for the first time!

Matt Phillips manages to pick out Karlan Grant but his cross is cleared by Trent Alexander-Arnold.

Alisson got bored. He tells Joel Matip to leave a header back from Jordan Henderson so he can join in.

Andy Robertson makes another run down the left but Darnell Furlong clears.

It's Trent Alexander-Arnold who takes it but he gets way too much whip on it and it's comfortably wide.

Andrew Mitchell: I know Big Sam has built his reputation on pragmatic tactics that get results, but how does he explain inviting Liverpool on and not having a single route out of defence when the ball does break the Baggies way? He's missing the “attack” portion of counter-attack.

Warringtini: If West Brom get any deeper they'll be in the River Mersey.

Jim Beam: WBA fans have to watch this rubbish for the rest of the season, what a terrible punishment. Big Sam is finished.

Curtis Jones is pulled back by Darnell Furlong on th edge of the box. A free-kick in a very good positon here...

Jordan Henderson clips another ball in for Sadio Mane and it's that man, Darnell Furlong, who is there again to head it away.

With all these players back defending for West Brom, he seems to be the one doing everything!

There is nobody even close to being up front for West Brom.

It's horrible to be organising a side so defensive as you know there is no way out.

Matt Phillips has the ball at his feet after a sloppy pass from Andy Robertson but there's absolutely nothing in front of him.

He lifts it straight back over to Fabinho.

I fear West Brom will struggle to score in this 6-4-0 formation...

Trent Alexander-Arnold... to Sadio Mane. Darnell Furlong again having to do some emergency defending at the back post.

Jordan Henderson whips a ball into the box now. Sadio Mane runs across Semi Ajayi to get there but his diving header is just wide.

Trent Alexander-Arnold pops up in the middle of the pitch and the wall of West Brom defenders are basically inside the box so he is able to stroll through before his shot is blocked.
