Salah added a second of his own in stunning solo fashion to well and truly put the game to bed before the hour mark, rendering Lucas Torreira's late strike a mere consolation.
Find out how all of the action unfolded courtesy of Sports Mole's minute-by-minute updates below.
Both teams have looked dangerous going forward but far from perfect at the back so far this term, so we should expect goals galore today - something this fixture usually guarantees anyway. At least one of the 100% records must end today, but whose will it be?
Kickoff is just five minutes away, so let's have a look at the team news first and foremost...
SUBS: Milner, Origi, Kelleher, Gomez, Shaqiri, Oxlade-Chamberlain, Lallana
SUBS: Mkhitaryan, Lacazette, Torreira, Martinez, Nelson, Kolasinac, Chambers
Alexander-Arnold does get a delivery on the money this time, swinging in a corner which Matip meets with a powerful effort which beats Leno and slams into the top corner!
Liverpool have seen the vast majority of possession and territory, but Arsenal have looked dangerous on the break and could easily be level at the break had they taken their chances.
This time it came from a corner, which Matip attacked really well to power into the top corner while Arsenal's defenders were too busy trying to thwart Van Dijk's threat.
The very best opening for the visitors fell the way of Pepe, who led a quick break, skipped away from Robertson and then put his finish straight at Adrian when he only had the keeper to beat. Pepe has also flashed a fine effort narrowly wide of the top corner and drawn another save from Adrian, while Aubameyang has come close to taking advantage of a rash piece of goalkeeping from Adrian.
If the hosts can make more of that avenue then there are plenty more goals in this one for them.
David Luiz with a very 'David Luiz moment' to concede the spot kick.
Salah collects the ball before skipping past Luiz all too easily and racing into the box. He gets in front of Monreal and then curls a low finish into the bottom corner - brilliant solo goal.
Aubameyang teed the diminutive midfielder up inside the box and Henderson initially got back to deny the first effort before he fired a second past Adrian.
It could have been different had Arsenal taken their chances in the first half, but Joel Matip's header just before half time and a Mo Salah brace after the interval took the game away from the Gunners.
Lucas Torreira did pull a goal back late on for Arsenal, but it was too little too late and Liverpool deserved a club-record equalling 12th successive top-flight win.
Thank you very much for joining Sports Mole for today's late kickoff as Liverpool become the first home team to win in the Premier League today, moving three points clear at the top of the table in the process.

From me, though, it is goodbye for now!
