Rob Edwards and his players are thoroughly enjoying their victory with the travelling Luton supporters.
It felt like it could have gone either way in the second half, but what a way to clinch victory right at the very end.

Image source, Getty ImagesWhat a hard fought game, really transitional, end to end, some really high quality bits and some scrappy bits too. A brawl, chances, it had everything.
There was the winning goal in the last few seconds, and Luton probably deserved that.
Everton had three clean sheets coming into this match and to concede two you can see the massive disappointment on their faces. Huge win for Luton.

The corner was so cheap to give away. Tarkowski miss-cleared the ball out for a corner.
A wonderful whipped in-swinging ball. It is just a second phase, Cauley Woodrow is lurking around the keeper Joao Virginia and the ball drops at his feet and he smashes it into the net.
I said there would be a winner!

Great FA Cup drama at Goodison, but it is Luton Town who march on to the fifth round courtesy of Cauley Woodrow's 96th-minute winner.
Sheff Utd 2-4 Brighton
The away end are chanting 'we want five.'
Eight minutes have been added on so Brighton have plenty of time to do it.
Cauley Woodrow
Cauley Woodrow has surely won it for Luton n the dying seconds of stoppage time at Goodison Park!
Scenes.
It is such a scrappy goal, and poor from Everton's perspective, but Rob Edwards' side won't care one bit!

Sheffield United have created a number of good guilt-edge chances. Before the game, if you offered the manager the chance to have seven guilt-edge chances, you'd be delighted thinking you put four or five away.
They are in the Premier League, Sheffield United need to step up in that regard.
Leeds 1-1 Plymouth
A replay will be needed to separate the Championship sides.
Leeds dominated the first half and scored through Jaidon Antony but Adam Randell scored in the second half for Plymouth so they will have to do it all again to determine who reaches the FA Cup fifth round.

Let's be honest, neither team wants to deal with a replay.

Can anyone produce the moment of quality needed to avoid a replay?

It is tense at Goodison. Neither side is going to want a replay in 10 days' time.
Everton 1-1 Luton Town
Into stoppage time we go and it is Everton who are pressing on in pursuit of a late winner.
Luton have made all their changes and are beginning to look stretched.

I don't think Sheffield United fans will mind if they never see this referee here again.
He's shown the attribute of being able to get his card out quickly.

It just shows how important it is to score goals when you're on top of the game.
Everyone thought Leeds were going to run away with it but Plymouth nick a goal.
