After opening the scoring inside 53 seconds, defender Martin Skrtel quickly scored a second goal with a fine header, before further strikes from Raheem Sterling and Daniel Sturridge emphasised the Reds' dominance.
Sterling added his second in the second half, with Arsenal's only reply coming from a Mikel Arteta penalty.
Here are the best tweets from a momentous day in this Premier League season:
Arsenal's Mesut Ozil started the day looking forward to the game, which would see his first ever appearance at Anfield. It was going to be one he'd remember...
Liverpool have a great attack but there's little to worry about in their defence and midfield. Arsenal must & can control the game.— gunnerblog (@gunnerblog) February 8, 2014
Our man @gunnerblog was confident that Arsenal could impress at Anfield, but they were in trouble straight away and fell behind when Skrtel nudged in a Steven Gerrard free-kick. But was he offside?

Liverpool didn't care though, and as the Reds swarmed forward at will, it wasn't long before Skrtel doubled their lead with a fine header from Gerrard's corner.
The identity of Liverpool's unlikely goalscoring hero wasn't lost on many.

Whilst it was all a bit too much for some...
This is ***ing ridiculous. #Afc— Piers Morgan (@piersmorgan) February 8, 2014
WAKE UP ARSENAL. For Christ's sake. We're getting absolutely shredded here. #Afc— Piers Morgan (@piersmorgan) February 8, 2014
Liverpool were in no mood to show any sympathy though, and quickfire goals from Sterling and Sturridge turned their 2-0 lead into a stunning 4-0 advantage, as the Gunners were completely overrun.
This is a crazy, crazy game. The Premier League leaders, who are unbeaten in 10 games, are 4-0 down inside 20mins.— James Pearce (@JamesPearceEcho) February 8, 2014
And typically, the jokes soon started flowing at Arsenal's expense:

Liverpool were in no mood to stop the scoring though, and after the break, Sterling broke clear to score his second of the game, burying a shot past Wojciech Szczesny at the second attempt:
Arsenal finally had a moment to cheer when Arteta converted from the penalty spot, but it was undoubtedly Liverpool's day, and the jokes were about to flow once more:

Ultimately though, the final word went to two managers with extremely varying moods:
Brendan Rodgers: "the performance was out of this world. The objective is to finish as high as we can. We will keep our focus."— Dominic King (@DominicKing_DM) February 8, 2014
Wenger: "It wasn't good enough. I include myself in that performance which raises questions about us. It's how we respond that matters."— Tony Barrett (@TonyBarretTimes) February 8, 2014
