A touch of Sunday League as ref Paul Tierney stops the game, we've got a flat ball. Anyone got one in their boot?

Roberto Firmino has a shot charged down, it runs out to Andrew Robertson but the left-back leans back and pummels it into the Anfield Road End.

Protocols observed.

Paul: Liverpool have a developed team, as they have already won the league & CL, whereas Utd are still a developing team. Have Utd got the best squad though, which will count this season?

Gee Em: Man utd already getting heavy into the tackles starting to be played around in midfield... Thaigo's smarts will be huge here.

He may not be happy but his side are clicking into gear. Thiago and Xherdan Shaqiri have got them into rhythm but there's no end product yet.

Jordan Henderson then does well to win a header from in front of Marcus Rashford.

The voice of Jurgen Klopp booms around Anfield and his tone is one of displeasure - followed by some frantic jumping up and down and waving of his arms towards his Liverpool players.

Not satisfied with something.

Luke Shaw sells David de Gea a bit short with a lay-off but the keeper just nonchalantly pings a side-footed pass all the way to Anthony Martial on halfway. Nice.

What's your go-to goal when you think of this fixture at Anfield?

Ruddock? Carragher OG? Forlan? Riise?

When Manchester United haven't got the ball they've gone into a 4-4-1-1 with Bruno Fernandes just in behind Marcus Rashford. Trying to overload the midfield area so Liverpool don't take charge of the situation.

No time to take a breath in that midfield, as it should be in such a game. Thiago lunges in but wins the ball and is trodden on by Scott McTominay. No harm done.

The first test of Jordan Henderson as a makeshift centre-back and he's left in the wake of Marcus Rashford like many a guest on Question Time. His cross is decent, but Fabinho is there to sweep it out and away.

Xherdan Shaqiri is the forgotten man of Anfield but he's started well, playing pretty deep in midfield but an influence early on. Thiago, on his home debut, sprays a fine ball out to the right but Trent Alexander-Arnold is shut out.

Quality from Sadio Mane to roll his man in midfield and Liverpool have numbers up. Xherdan Shaqiri, who hastened the departure of Jose from his suite at the Lowry with a few goals in this fixture, shapes to shoot but then finds Andy Robertson who duffs a cross into the side-netting.

If only it was a full house. If only the pubs were open. Ah well.

Manchester United make a bright start but a cross from the right flashes through the penalty area without causing alarm.

And we're off! It's almost exactly a year since these sides met at Anfield - Liverpool won and were 30 points ahead of their rivals.

Times have changed.

YNWA rings out around an empty Anfield, with added poignancy given the recent loss of Gerry Marsden.

His passing will be marked before kick-off. The sides are out.

There will be many reading this who won't even remember that season.

I’ve not seen Liverpool play a different way for about two years now, they have their way of playing and their issue is when they don’t do it well they tend to come up with some bad results.

You take Jordan Henderson and that intensity out of that dynamic midfield and they’ll get caught. Then you don’t have the comfort blanket of Virgil Van Dijk then every now and then when you do get caught. Man United will have their chances and Liverpool will know that.

As the sides line up in their respective tunnels, a reminder that we asked you to name your combined Liverpool-Man Utd XI - and here it is in all its glory.

It's not often the centre-backs dominate the pre-match chat but fans of both clubs seem a bit perplexed by the team selection back there.

Liverpool have gone for Jordan Henderson alongside Fabinho, while United have gone for Victor Lindelof and not Eric Bailly.
