Former Liverpool left-back on BBC Radio Merseyside
I’m just wondering when Mohamed Salah is going to get into the game.
He’s playing up front and sometimes you think he doesn’t quite like playing up there, but for the team it’s working wonderfully well.
Liverpool 2-1 Arsenal
Sadio Mane's pass to Trent Alexander-Arnold is well-read by Alex Iwobi and Arsenal can counter.
Liverpool quickly get into shape though and the visitors are forced back to Bernd Leno for a more patient build-up.

Xherdan Shaqiri plays a lovely ball through the middle for Georginio Wijnaldum but Bernd Leno reads it and comes out to the top of his box to clear.

Tim: Oh Arsenal, you give me 30 seconds of hope... then pure misery!
G Yiannakopoulos: Disgruntled LFC supporter...I go to the kitchen to make a cup of tea and miss Bobby's two goals in 2 minutes!
Liverpool 2-1 Arsenal
Sadio Mane gets past Stephan Lichtsteiner but chooses to shoot from a tight angle on the left rather than cutting it back into the centre towards a teammate. Comfortable save for Bernd Leno in the end.

Arsenal posed the question by going ahead - and Liverpool answered it by turning it around within minutes to lead.
Shocking defending by Arsenal as well as great skill from Roberto Firmino.
Fair to say, on every level, that Arsenal have not come to Anfield to defend.
Anfield is currently exultant.

Andy Robertson is harassed by Ainsley Maitland-Niles and Stephan Lichtsteiner but the Liverpool left-back does well to hold them off.
Arsenal are pressing high though and putting pressure on Liverpool's defence.

We've not had a goal for four minutes. Rubbish.

Javel: WOOOOOOH Firmino x2!!! You beautyyyy!
Khan: Lovren is so leaky, need Gomez back fast. Good thing we have Firmino!
Sushant: If there ever was a player transformed by a change of manager, it has to be Firmino - what a transformation under Klopp - looks a world beater

The ball comes into Roberto Firmino's feet again and there's a huge roar of excitement from Anfield. He's been electric so far.
But it's Arsenal who are attacking and Georginio Wijnaldum has to make an inch-perfect tackle on Aaron Ramsey to deny him a chance to shoot in the box.

Alex: Imagine if teams from North London had a backbone?
Peter: Of course, if Arsenal are going to do a repeat of the shambolic defending from Old Trafford...
Fabian: Well, this must be a goals galore.
What is going on!?
Roberto Firmino
What. A. Goal. Absolutely incredible!
Roberto Firmino weaves in and out of three Arsenal players, runs into the box and slots it past Bernd Leno on his left.
An astonishing individual goal!

We asked for goals, we're getting goals!
Roberto Firmino starts the move by slipping it through for Mohamed Salah. Arsenal's defence stick toes out to stop his run but it somehow ricochets favourably for Firmino in the centre. The Brazilian literally just has to tap it into an empty net! No-look goal too.

Dejan Lovren gives the ball away carelessly in midfield and Alex Iwobi drives into the space before firing an inch-perfect ball across the box. Ainsley Maitland-Niles is waiting at the back post, unmarked, to slide in and tap it into the back of the net.

Fabinho gives the ball away to Alex Iwobi on the edge of the Liverpool box. Trent Alexander-Arnold sprints back to cover but Iwobi still gets the shot away, forcing a low save from Alisson on his left.
The corner is delivered in but Pierre-Emerick Aubameyang and Shkodran Mustafi are both offside as the ball bounces dangerously around the six yard box.
Liverpool 0-0 Arsenal
Sadio Mane and Stephan Lichtsteiner have a bit of a falling out. The Liverpool forward appeared to elbow the Arsenal defender and he's not happy about it.

Sadio Mane's pace beats Arsenal's defence and he surges into the box before laying it off for Roberto Firmino. The Brazilian hits it first time and Mohamed Salah tries to flick it past the keeper on its way but it skims the side-netting.
