Marine v Tottenham (17:00 GMT)
The was the scene in Crosby as the teams arrived at the Marine ground.
Marine v Tottenham (17:00 GMT)
Former Liverpool defender and Crosby resident Jamie Carragher, who is sponsoring the dugouts and warm-up tops: "The thought of Jose Mourinho facing the club named after the pub a few hundred yards down the road appeals to every fan with football stitched into their soul.
"The ground is a long way from the glittering arena Spurs call home.
"The first challenge will be getting their luxury coach down tiny, cramped College Road to get anywhere near the ground, let alone park it once they're there.
"Then the players will have to get changed in a function suite - hastily converted into a dressing room - before going out to play on a pitch which, when I last visited in December, was more mud than grass."

FT: Crawley Town 3-0 Leeds United
Jermaine Beckford
Ex-Leeds Utd striker on BBC Radio 5 Live
It's not the fact that Leeds lost, it is the manner in which they lost. They were pretty toothless in the final third and that's not something that we're used to seeing. We are used to seeing Leeds peppering the opposition goal but we didn't see that today.
Leeds almost ran out of options and ideas once they got to within 22 yards of the goal.
But I can't see Marcelo Bielsa being too kind to these guys - he'll have them in training tomorrow morning and everything they did wrong today they will be making right.
Cheltenham 2-1 Mansfield (aet)
Cheltenham Town go through to round four!
William Boyle's header after 110 minutes completed the turnaround for Michael Duff's side.
FT: Crawley 3-0 Leeds
More from Crawley boss John Yems: "It's not me v Bielsa. It's all the about the team. I've gone past that stage - it's nothing to do with me. He does what he does, and I do what I do. He was very complimentary afterwards, but I suppose if you lose 3-0 you can't do anything but.
"I don't think it's sunk in yet. The pity is that there is no supporters here. I've been telling the lads to go out and enjoy tonight, but you can't go out anywhere so that shows how up to date I am with things! But no, listen, it is what it is. Hopefully we can move onwards and upwards.
"Nick Tsaroulla is another one, alongside Max Watters, a few people have said 'what am I doing signing those?' but sometimes you get these lads who want a second chance, and they come on and perform like that, and it is brilliant for them, because they've had enough knocks so let them enjoy the moment."
Marine v Tottenham (17:00 GMT)

Tottenham XI: Hart, Doherty, Alderweireld, Rodon, Davies, Sissoko, White, Gedson, Dele, Lucas, Vinicius.

Marine make two changes to the side that started the victory over Havant & Waterlooville in the last round.
Former Liverpool defender David Raven, who made his Reds debut against Spurs in a League Cup tie in 2004, starts. Ryan Wignall, a two-time FA Youth Cup winner with Liverpool, is on the bench.
Cheltenham 2-1 Mansfield
Everyone is up for Mansfield as a free-kick is launched forward, but Cheltenham are doing enough in defence.
The hosts then break forward and have two players closing in on goal, but Alex Addai takes too long on the ball and Mansfield recover.
Two minutes of added time at the end of extra time for Mansfield to find a goal.
FT: Crawley 3-0 Leeds
Crawley Town manager John Yems on BBC Radio 5 Live: "It's easy to say it now, but I've been saying it all week, we were never going to sit off. We were always going to have a go at them and I know we've got some good players, and we've worked hard all week, and on the day our performance was better than them and we deserved the 3-0.
"At half-time I just said keep doing what we're doing, and have a bit more belief in ourselves. We've seen all season that we've got goals in us. We had a game plan and we stuck to it and the lads really worked their socks off and got their rewards.
"All of us, all the backroom staff, worked on it, but it is all about the players. They've bought into it and we've put our ideas down and they've executed those, and if you keep on doing that you get results."
Here are three goals that Crawley scored to defeat Leeds and reach the fourth round.
They will no doubt have them on repeat around Sussex tonight...!
FT: Crawley Town 3-0 Leeds United
Terry Butcher
Ex-England captain on BBC Radio 5 Live
Leeds let themselves down in the second half by not going on to fulfil the promise that they'd shown in the first half, because they were a real privilege to watch.
They just didn't test the keeper enough, but you've got to keep that going and get the first goal. Whoever gets the first goal in a cup tie is going to gain confidence and that goal seemed to rock Leeds.
Fair play to Crawley, they are a good outfit that are well led on the pitch and off the pitch.

Ex-Leeds Utd striker on BBC Radio 5 Live
Fair play to Crawley - they were absolutely brilliant from the first whistle to the final whistle. They took the game to Leeds and made it a bit more physical than Leeds would have wanted.
Every single Crawley player was absolutely brilliant.
Cheltenham 2-1 Mansfield
Nigel Clough makes his third change, sending on James Clarke with five minutes of extra time to go.
On the balance of play Cheltenham would be worthy winners, but can they see this out?

Terry Butcher
Ex-England captain on BBC Radio 5 Live
Crawley took full advantage of Leeds trying to get back into the games after making three substitutions.
People will say that Marcelo Bielsa treated it like a training game, but I don't think he did. He was let down by his players, but to make three changes at half-time is a bold gamble.
William Boyle (110 mins)
That could very well be the winner for Cheltenham!
The comeback is complete, as defender William Boyle heads in from a long throw by Ben Tozer.
What have Mansfield got left?
Marine v Tottenham (17:00 GMT)
There's a huge crowd outside the Marine ground to greet the Tottenham players off their bus! Some of the young lads in Jose Mourinho's squad can't help but smile.
Cup fever.
Cheltenham 1-1 Mansfield
A change for Mansfield as defender Aaron O'Driscoll is introduced.
It's all beginning to feel a bit frantic as neither side can take control of the ball in search of a winner.
10 minutes to go.
FT: Crawley 3-0 Leeds
Leeds midfielder Ezgjan Alioski on BBC Radio 5 Live: "I can't find my words right now. We are really disappointed and it wasn't the result that we wanted. Especially me I'm really sad, we took the game really seriously and we wanted to win and go on a run so it is disappointing.
"Crawley played the game of their lives, and congratulations, and to beat us 3-0, I still can't believe it.
"The manager said what he wanted to say. It's important for every player to know what this means. He is sad, and the players are sad."
FT: Crawley 3-0 Leeds
Alistair Bruce-Ball
BBC Radio 5 live commentator
Leeds fans will be so delighted with what Marcelo Bielsa has done during his time at the club, playing the football that they are, anything like this and they will always give him leeway.
This clearly wasn't a priority and he works his players very hard. They made seven changes, and if you look at the changes he made at half-time they were about rotation and giving the young players a chance. therefore you are taking a chance with your place in the FA Cup but who are we to question Bielsa.
