Adam: How is that not a penalty? VAR a waste of time. What a disgrace.

Mike: Can someone please explain to me how that is not a clear and obvious handball? I just do not understand anymore.

JavelBleach: In what universe is that blatant handball not a peno?!!?

Bukayo Saka finds Gabriel Martinelli in the box but the Brazilian flashes a ball across goal. Ben White keeps it in but then the referee stops play because Trent Alexander-Arnold is down injured.

Arsenal are decent at the back at the moment aren't they. Takehiro Tomiyasu makes sure Mohamed Salah can't get onto a Jordan Henderson ball over the top.

Liverpool are struggling to connect the dots. Van Dijk just hasn't really got a pass on, he passes to Tsimikas who passes it back to him because there is nothing in front of him.

I have wondered if a time might come for Trent Alexander-Arnold to be tested out in other positions to see how he does there.

Bob: Klopp needs to admit defeat and get a real right back, put TAA in midfield if need be.

Andy: Liverpool certainly being unpredictable. Didn't expect us to score that fast!

Now Arsenal fans are unhappy as Bukayo Saka gets a whack in the face from Konstantinos Tsimikas but there's no punishment.

Good start to this game for the neutrals. And Arsenal fans.

That's a big shout, Gabriel's arm was in an unnatural position and his arm is flailing but it's waved away.

Liverpool want a penalty as Luis Diaz volleys a cross against the arm of Gabriel, whose arm was very much out.

VAR decides not to get involved so it stays a non-penalty. Yikes.

It was close range but you've seen them given.

Gabriel Martinelli has been directly involved in seven goals in his last seven Premier League appearances at the Emirates, scoring four times and providing three assists.

What a player the 21-year-old Brazilian is becoming.

Xhaka asks the question of Alisson and he answers it.

Should that be 2-0? Maybe. Ben White flies down the right - is he above TAA in the England pecking order yet? - and crosses for Granit Xhaka, who has time but his effort is saved by Alisson.

Maybe Xhaka was offside anyway.

Rhys: Liverpool fans can only really blame themselves. They said VVD was best in the world, they said Trent was best in the world, they said Alisson was best in the world, they said Nunez would be a better signing than Haaland. They’ve overhyped and now reality is hitting.

Trent Arnold-Alexander crosses from the corner and Virgil van Dijk's header is well over the bar. He was near the edge of the box.

A Liverpool corner courtesy of a bad first touch from Gabriel Martinelli. Bit of a gift set-piece this.

Matt Turner can sit back down. Aaron Ramsdale is patched up and will play on.

Alisson seems to be getting quite agitated and that is spreading through the pitch. It just doesn't seem harmonious at Liverpool at the moment.

Michael: VAR trying to find an excuse to disallow Arsenal's goal. Even they can't help Liverpool's awful defence!

Paul: I see the Trent haters are out again. The lad needs help: it was 2 on 1 back there, what's he meant to do?

Oh oh. What's happened to Arsenal keeper Aaron Ramsdale here? He's injured.

It looks like he hurt himself while taking a goal-kick and then again as he raced out of his box.

Matt Turner is getting ready.
