Despite making a promising start to the season, the Gunners were well and truly humbled on Merseyside as they slumped to an embarrassing 5-1 defeat.
What makes the loss all the more painful is the fact Arsenal actually took the lead and it came virtue of Ainsley Maitland-Niles, who arrived at the back-post to claim his first goal for the club.
Rather than inspiring the Gunners onto victory, however, it seemed they simply poked the wasp's nest and Liverpool proceeded to exercise their revenge within minutes.
By the time 20 minutes had passed, the Reds found themselves in the lead with Roberto Firmino scoring twice, one under fortuitous circumstances and the other thanks to some brilliant skill.

Sadio Mane then proceeded to write his name on the score-sheet - despite a controversial moment with Stephan Lichtsteiner - before Mohamed Salah made it 4-1 with a penalty before half-time.
Firmino was then given the opportunity to compete his hat-trick after the break, becoming the second player to beat Bernd Leno from 12 yards on the night.
In truth, Arsenal didn't offer much in response and the closest they came to scoring was an offside opportunity spurned by Pierre-Emerick Aubameyang.
Aubameyang's terrible statistic
It wasn't a vintage performance from the Arsenal striker to say the very least and that embarrassing moment - only saved by the linesman's flag - summed up his evening.
However, it got even worse for Aubameyang as a humiliating statistic emerged about his display, suggesting his performance was as uneventful as it was disappointing.
Gary Lineker even felt the need to tweet about it after the game with Aubameyang touching the ball just 13 times and six of them came from kick-off.

Thirteen touches, really Pierre-Emerick?
Although the Arsenal forwards didn't get many opportunities to influence the game, you would expect far more activity from your lead striker and he was hooked by Unai Emery before full-time.
It's no surprise that the statistic has gone viral and heat maps focused on the centre-circle make for rather amusing viewing after the match.
Nevertheless, he remains the top goalscorer in the Premier League and Arsenal fans are more than aware of his talent against a number of top teams.
Fans will just have to consider it an off-day and the autopsy on Arsenal's overall showing will begin in the coming hours and days.
Arsenal have made big strides under Emery but their performance at Anfield was reminiscent of the Arsene Wenger days that had sparked so much frustration.
Perhaps get a little more involved next time, Pierre-Emerick.
