Mason Greenwood fires a ball across the six-yard box. There's nobody on the end of it but it comes back to Diogo Dalot in the centre and he ends up blasting it over the bar.

Fred and Tahith Chong are on for Man Utd. It's Nemanja Matic and Anthony Martial who go off.

Josh Hammond: Calling it now: Luke Shaw to score number 6 with an overhead kick.

Back underway at Prenton Park.

Liverpool make 11 changes to the side that started against Wolves on Thursday with Fabinho among the starters.

Liverpool XI: Adrian, Williams, Matip, Lovren, Larouci, Fabinho, Chirivella, Jones, Minamino, Elliott, Origi

The fifth and final goal of the half.

Right, come on then Josh Earl, who's scoring next?

Pete: Stuck £50 on United’s first 4 goalscorers being Maguire, Dalot,Lingard & Jones. Now I’m a millionaire, I’m handing in my notice tomorrow.

That's the dream Pete!

Shrewsbury manager Sam Ricketts speaking with BBC Match of the Day: "It is going to take the lads five or 10 minutes to relax into the game. But I will be making the point that you certainly want 11 men on the pitch and basically stay in the game for as long as you can.

"I'm excited - I have gone from non-league all the way to the top and you want to test yourselves against the best. and as a manager it is no different.

"It's going to be a real tough game whoever they put out there will be international players but ult this is what you want to do.

"This is why the first and second round of the FA Cup - every round we play we told the lads you never know what is around the corner - and then we got the plum tie."

No surprises so far today. Will Shrewsbury boss Sam Ricketts (centre) mastermind one against runaway Premier League leaders Liverpool?

Team news from that tie is out in the next few minutes.

Phil Jones scoring.

It's the first time in 13 months Manchester United have scored five goals in one game.

And it's the first time they have scored five first-half goals since February 2001 against Arsenal in the Premier League, when Ole Gunnar Solskjær scored the fifth goal.

TravellingMonkey: Emma, at 14.39 I Tweeted Jones (possibly) scoring an OG, does that count in this bbcfacup thread? So we've had 2 deflected goals in 1st half, not bad, just remember form and opposition.

You know what, I'm feeling generous Travelling Monkey. I'll give you that.

Ole Gunnar Solskjaer will be thrilled. The next bit for him now will be getting a clean sheet and making sure everyone gets off the pitch fully fit.

They have been clinical, started off with two shots and two goals. They have come here and been thoroughly professional, done their job and been superbly led by Harry Maguire.

Five goals here already. Another four at the Etihad this morning. We're raking them in!

Harry Maguire has both scored and assisted in a single game for the second time in his career, last doing so for Sheffield Unittd in the EFL Trophy against Notts County in October 2012 (2 goals, 1 assist)

Jesse Lingard has scored twice in his last 42 games in all comps in the last 365 days.

I feel sorry for Scott Davis in the Tranmere goal because in all of the goals he can't have done anything. What a finish from Anthony Martial, bending it in. Great goal.

Well. That was fun!!
