Wilfried Gnonto is a whisker away from making contact with a lovely ball over the top from Marc Roca.

Tom Sang can't get near Gnonto's shadow at the moment, let alone Gnonto.

A half chance for Cardiff as Mark Harris heads wide from Sheyi Ojo's cross.

Their best move of the game, but that was always going wide.

Jack Harrison is getting so much space!

He finds Rodrigo this time and the forward fires over.

Another warning shot for Cardiff.

If they don't improve a second Leeds goal is coming.

Dean: I said over the weekend that Gnonto is the bargain of the season, that goal is why, he is going to be some player!!

Anon: Shades of Di Canio's goal v Wimbledon there.

Baz: Gnonto was superb v Villa. He’s not going to be at Leeds very long!

Wilfried Gnonto again... This time he splits Cardiff's defence with a pass and Rodrigo looks to burst clear, but Jac Alnwick was off his line swiftly to clear.

A lovely run by Rodrigo and a clever reversed pass, but Sam Greenwood wasn't on the same wavelength and the chance goes begging.

Cardiff finally get the ball, Jac Alnwick calls for calm and to slow things down and then kicks the ball straight out of play.

They are struggling.

As soon as you get the ball, you've just got to get it to Wilfried Gnonto. Not only do the players want to get it to him, but the fans do as well.

Wilfried Gnonto is terrifying Cardiff and every time he gets the ball the noise levels go up in Elland Road.

Leeds are continuing to push Cardiff back.

They have started at 100mph. The Bluebirds can't cope.

I need to get focused on the game... but... I can't get enough of the goal, it's just absolutely brilliant.

Shades of Paolo Di Canio.

To echo my friend Michael, wow! Just, wow!

What an unbelievable start for the home side!

You know when I said there might not be anything tonight to add to the Leeds FA Cup showcase reel? I take it all back!

Wilfried Gnonto has just smacked in an absolute worldy of a volley to lift the roof off this place!

He was Leeds' standout player at Villa on Friday. The kid looks some player.

You won't see too many better goals tonight, this week, this season.

That was astonishing technique. That is an astonishing goal. He scissors it, technically you're not supposed to do that but he did it and he did it brilliantly. What a goal, what a start to this game.

Cardiff plans out the window.

Referee Thomas Bramall gets us under way.

A packed house to see a televised FA Cup replay against a team from the second tier. Not a bad effort, that.

The Leeds fans are making themselves heard ahead of kick-off with a rendition of 'Marching on Together'. It's rousing stuff.

Cardiff have brought a few with them too and they won't be shy. Should make for a cracking atmosphere.

The teams are in the tunnel.

We are four minutes from kick-off at Elland Road.

Who will be the penultimate team to reach the fourth round of the FA Cup?

This is a game that Leeds should be winning. They are playing at home against a lesser Championship opponent. A team in Cardiff that are struggling in 21st in the Championship which is why the manager was relieved of his duties at the weekend.

If they were to lose the game tonight, it would be a real dent in their confidence going forward because they have to stay in the Premier League. The remit for this club is to stay in the Premier League.

They are struggling at the moment, they haven't won since 5 November which is a long, long time. They had a great week when they beat Liverpool at Anfield and then came back here to Elland Road and beat Bournemouth.

They are conceding far too many goals and not scoring enough which isn't a recipe for any club that wants to stay in the Premier League. They are sitting in 14th position at the moment, they are two points from the bottom three. They are clearly in a relegation fight.

This season, unlike any other, the Premier League is so condensed at the bottom, almost half way up the table you could say could get drawn into that bottom three dog fight. It's one that Leeds United can't afford.

This place is filling up nicely now. The two sides are pretty much done with their warm-ups and heading off for some final words before we get started.

The big screen here is playing all of Leeds' greatest FA Cup hits - the 1972 winner from Allan Clarke, Jermaine Beckford's goal at Old Trafford in 2010, Ross McCormack scoring against Tottenham in 2013.

With all due respect, I can't imagine anything that happens here tonight will get added to the reel, but you never know.

They might have been fortunate to earn a replay, but West Brom took full advantage last night against non-league Chesterfield.
