Booking for Liverpool defender Nathaniel Clyne for deliberate handball which brings an Arsenal attack to an end.

Relentless end to end action at Anfield. Theo Walcott evades a challenge before dragging another chance wide. 

Alberto Moreno wastes a great chance for Liverpool in front of the Kop by firing well over. This is not going to finish 2-2.

Early chance for Arsenal to take the lead for the first time. Mesut Ozil, king of the assists, plays a wonderful ball to Joel Campbell but the Arsenal forward blazes over the bar at the back post.

Back under way. Anyone fancy another four goals?

Matt in Koh Chang, Thailand: Game kicked off at 3 am here....my mate who lives here didn't wake up until 3.25 so we missed all four goals in the Arsenal game.    

Dan, from London: Whichever way you dress it up, maligned Mignolet has conceded twice at his near post. Hard to defend him. Dan, London. 

Adam, Darlington: The premier league might not be the best for quality. But it is second to none for entertainment. Wouldn't change it for anything.

"Think everyone needs a lie down never mind a half-time cup of team. A breathless, runaway first half ends with Liverpool and Arsenal level.

"Liverpool look a real threat and have played with real energy but their defence and goalkeeper Simon Mignolet are accidents waiting to happen - and we didn't have to wait too long.

"An absolute cracker in a knockabout sort of way."

Wow. What a half.

Emre Can has been excellent for Liverpool as has Adam Lallana. Can is 25-yards out when he tests Petr Cech again. Liverpool are finishing the half strongly. Moments later Roberto Firmino goes close to his hat-trick with a shot on the turn. 

Three minutes of additional time.

Tom Allen: Benteke should try as centre back. Might get a start and couldn't be any worse.  

After four goals in the space of 15 remarkable minutes, we haven't had one for 20 odd minutes but what's this? A patient build-up by Liverpool and Roberto Firmino is denied a hat-trick by Petr Cech.

Moments later Arsenal break and Theo Walcott's effort is deflected behind for a corner.

Just over five minutes of normal time remaining in the first half. Lots and lots for the fans to talk about at half-time. But just where do you begin?

"Liverpool manager Jurgen Klopp and his Arsenal counterpart Arsene Wenger just had an amiable chat in Anfield's technical area - they are probably as light-headed as everyone else in the stadium.

"Defending of the lowest quality, dreadful keeping from Liverpool's Simon Mignolet and a wonder goal from Roberto Firmino. All happening.

"And Mignolet about to sign a new five-year contract. Really."

Arsenal are starting to boss the game for the first time. Another Gunners corner...and more confusion in the Liverpool defence as the ball fizzes across the six-yard area.

Shanmugaraja CK: I am expecting a tennis score at Anfield! 7-6 to Arsenal.

Venkat kartik: There's no way Liverpool can win a game, let alone the league with defending like this. All the good work undone.

Jurgen Klopp and Arsene Wenger are deep in conversation on the touchline. It's all very amicable and Wenger is even smiling. No wonder. Poor defending by Liverpool has twice allowed the Gunners a way back into this.

How did Arsenal miss that!

A huge escape for the hosts as Olivier Giroud somehow misses an open goal in front of the Kop following Hector Bellerin's cross.

This is an incredible match.
