Georginio Wijnaldum - playing in midfield today after the up-front experiment in Barcelona - almost plays in a great through ball but Fabian Schar cuts it out.

And now Jamaal Lascelles heads Andy Robertson's cross out for a corner.

Richard Browne: Shaqiri is the other option. Why Klopp has stopped playing him is a total mystery.

Dejan Lovren immediately makes a mistake, clearing the ball straight at Salomon Rondon - but he just gets it back to Alisson in time.

Liverpool get the second half under way.

Salomon Rondon is having some banter with the fourth official as he comes back out.

Everyone is back out for the second half. Almost time to go again.

Johnny Magrinho: Liverpool desperately need a back up for Firmino. Sturridge is so far off the pace it's embarrassing watching him try to play football and Origi just never plays well enough. Can't blame Klopp for trying Gini up top the other night - what other options does he have?

Jurgen Klopp - as usual - has been fired up on the touchline.

Daniel Sturridge has been getting an ear-bashing, as did the fourth official when Mo Salah was cleaned out in a tackle, although the Liverpool manager was swift to order the Egyptian to calm down as it looked like tempers could boil over.

Klopp will at least be happy with the scoreline so far.

Very strange half, almost three parts. Liverpool scored and seemed to be in control. Then all of a sudden Newcastle went forward and got a deserved equaliser. It felt like a cup tie at that point and then Salah then put Liverpool ahead again with a fine finish.

Liverpool are generally in control but they do look a bit vulnerable defensively when Newcastle go forward.

Looks like maybe Trent Alexander-Arnold should have been booked, but not sent off.

This is from the FA's rulebook...

"If the referee plays the advantage for an offence for which a caution / send off would have been issued had play been stopped, this caution / send off must be issued when the ball is next out of play, except for the denial of an obvious goal-scoring opportunity when the player is cautioned for unsporting behaviour."

Liverpool lead at the break. They are 45 minutes away from going top again.

Newcastle defender Fabian Schar is booked for stopping Jordan Henderson from taking a quick throw-in. That's his 12th Premier League booking this season.

We're into added time now.

It looks like there are some Liverpool fans in the posh seats just behind the press box. It appears they celebrated when Mo Salah scored Liverpool’s second and the home fans sat nearby are clearly not impressed.

Newcastle have had five shots on target to Liverpool's three.

First Newcastle attack in a while, Salomon Rondon is picked out with a long ball and does well to hold off two defenders before getting a shot in, which is saved by Alisson.

Harry Gale: If the Premier League were a F1 race, Liverpool and Manchester City would now be lapping the rest of the field.

Fabian Schar loses the ball to Jordan Henderson, Fabinho and Sadio Mane link up to get Henderson back on the ball but he loses the ball just as he reaches the Newcastle box.

Newcastle know where Robertson is going but nobody has attempted to get anywhere near him.
