It already has the feel of a side playing at 5-0 up. Liverpool are stroking it around with utter freedom as United forlornly chase shadows.

Utter dominance. Unsurprising Liverpool have scored a second after what we saw leading up to the goal.

In the five minutes before Mo Salah's strike, Liverpool enjoyed 86% of the possession and spent 50% of that time in Manchester United third.

Sir Kenny is grinning from ear to ear.

Sir Alex looks like someone has just urinated on his Christmas presents.

Just depends how many Liverpool fancy scoring tonight.

The gulf is huge.

That is an absolutely magnificent piece of football from Liverpool.

It's a great touch by Salah and when he gets into that sort of situation you know he's not missing. The pass from Sadio Mane is absolutely world class.

Liverpool have been totally dominant and they look like they can cut Manchester United open at will.

Harry Maguire looks anguished as he shouts instructions to team-mates. Nobody in the away side has really got a grip of this yet.

It remains all Liverpool.

Another home corner is cleared but only as far as Jordan Henderson, who volleys over from range.

Every single Manchester United looks rushed at this moment in time.

Nobody wants to take responsibility. They are giving away the ball far too easily.

Andrew Priestley: If that is to be the final time we see Paul Pogba in a Manchester United shirt, then the manner in which he left the field of play this evening sums up his time at the football club. Limp.

It must be wonderful to be a Liverpool fan watching this. Especially ones who remember the 1990s and 2000s, when United were dominant. Watching this United panic and hack away aimlessly as Liverpool come at them again and again.

Andy Robertson's corner is deep and falls to Fabinho, who goes for glory with a volley but fails to properly catch it. United clear.

Sadio Mane shuffles his way into a shooting chance and fires an effort that deflects wide. Corner.

Jesse Lingard breaks from the Liverpool defence to try and get on to a Diogo Dalot forward pass, but the ball skips ahead of him and through to Alisson.

Liverpool also took the lead in the fifth minute on Old Trafford, Naby Keita (4:42) scored three seconds later than Luis Díaz (4:39) today in that 5-0 Liverpool win.

It is all Liverpool.

United know they can't afford to concede another soon. If they do, this will start to shape up just like the return game at Old Trafford.

Luis Diaz threatens again, but his tame looping header from a Thiago cross loops over the bar. The chance came after the half-clearance of a Liverpool corner.
