Shrewsbury midfielder Richie Wellens has been speaking to BBC World Service about the match though.

He made one appearance for United before leaving the club in 2000.

On being told by Sir Alex Ferguson that his contract would not be renewed:

He said: “I can feel it in my stomach still, being in the manager’s office and hearing him say: ‘We are not giving you a new contract’. That will stay with me forever, that gut-wrenching, horrible feeling.

"They hold a special place in my heart, even though it took me a couple of years to get over the disappointment of being released. I didn’t go back to the club to watch games, because I wanted to get over it and make a career for myself."

Imagine your frustration...

You are a Manchester United fan and your team have just drawn them in the FA Cup fifth round.

But - because of a three-minute cameo for Doncaster against Stalybridge - you are cup tied.

Richie Wellens, we feel for you.

The ex-United man, now at Shrewsbury, will have to watch from the stands.

That is a great wig... I'm hoping it is a wig anyway.

A little less than 20 minutes till kick-off and the atmosphere is building at Greenhous Meadow.

Shrewsbury defender Jack Grimmer scored the winner in the previous round. How this lot would like more of the same...

Tell us who you support and how you would sum up your season in a movie using #bbcfacup, external or text 81111.

Neil Southey: QPR. The Lost Boys

Mike Rookery: For #watfordfc, external the film would have to be Troy Story. We'd watch it at the Odeon Ighalo.

Dave Ramshaw: For Carlisle United yet again has to be Waterworld

Shrewsbury manager Micky Mellon on BT Sport: 

"We've been looking forward to this since the draw was made. We believe we have a chance. We have got to believe we have a chance. If we stick to the gameplan and do them well we could have an opportunity. Playing United under floodlights, the adrenalin will be pumping."

Manchester United manager Louis van Gaal on BT Sport remarking on his job speculation:

"You can't close your eyes and read a lot of media. It's better not to read. I have a press officer and she reads the media for me. I can cope with that and hope my players can cope with that."

Manchester United manager Louis van Gaal on BT Sport: 

"It's always a big game in the FA Cup. I think that Man Utd always have to win - especially in the FA Cup. 

"We have not won this for a long time and it's very important for the club and fans."

On their fixture schedule:

"It’s a difficult programme because we're in all the competitions. There's not much recovery time and we have 13 injuries. It's a small group that have to play these matches."

Shrewsbury's starting XI in their last League One outing - a 3-2 win at Blackpool - cost in the region of £10,000.

Manchester United's starting XI in their last Premier League match - a  2-1 loss at Sunderland - cost around £169m.

David v Goliath? Just a bit..

Great effort Girish. Top marks for effort...

We want to know what movie sums up your club....

Like a bowling green Louis... don't start blaming the pitch.

Van Gaal is speaking to the television cameras as we speak, sporting an extraordinary quiff - almost in the style of the Wembley arch.

Ian Megennis: this season Newcastle are the pile of gold in the closing scene of The Italian Job. The doors have been blown off too!

Simon Alborn: I'm a Leicester City fan. Field Of Dreams for us this season.

Adam Turpin: It would be.... Forest Gump. Life is like a box of chocolates, you never know what you are going to get. Southampton.

Manchester United manager Louis van Gaal - rather like his team - has been stumbling along in recent weeks amid the fog of speculation surrounding his future.

There has appeared no great appetite from United's executive vice-chairman Ed Woodward to sack the Dutchman but it is hard to see how he could possibly survive defeat here tonight in the FA Cup fifth round tie against Shrewsbury Town.

They are currently languishing in the bottom four of League One. Win tonight, though, and surely it is all over for Van Gaal.

We asked what movie would sum your season up?

Financial Coldplay: Ghostbusters 2 (Manchester City, playing in ghost green?)

Matthew Love: Titanic. (An Aston Villa fan perhaps?)

Richard Tugwell:  Honey I shrunk the attendance. (Judging by the empty spaces at Ewood Park on Sunday, perhaps Blackburn?)

We also want to know which club you are talking about. The above didn't, so I've put my guess in brackets. Tweet #bbcfacup or text 81111.

Manchester United make four changes from the XI that started in the 2-1 defeat at Sunderland.

Sergio Romero, who played in goal in the Europa League last week, starts again with David De Gea injured. Guillermo Varela, Ander Herrera and Memphis Depay are also selected.

Shrewsbury defender Jack Grimmer is fit and is selected. Former Manchester United midfielder Larnell Cole, on loan from Fulham, is on the bench.

Man Utd XI: Romero, Varela, Smalling, Blind, Borthwick-Jackson, Schneiderlin, Herrera, Memphis, Mata, Lingard, Martial   

Shrewsbury XI: Leutwiler, Grandison, Whitbread, Knight Percival, Grimmer, Whalley, Black, Ogogo, Brown, Akpa Akpro, Mangan  

The team news is in.

No surprises for Manchester United with Sergio Romero starting in goal.
