Wilfried Gnonto is down injured for Leeds. He's holding his shoulder after an awkward landing. Hopefully nothing too serious.

I don't think we'll be waiting long for the first goal. Both teams are really up for this. Everton have woken up.

Oliver Norwood plays a long cross field ball for Ben Brereton Diaz who picks out Gustavo Hamer but he can't bring it under control so the chance is gone.

Dwight McNeil goes down after being caught by Albert Sambi Lokonga's outstretched leg.

I'm not sure it needed to be that high, with the ball very much on the ground, but the Luton midfielder escapes any punishment.

William Osula, who scored two goals against Gillingham in the third round, has been particularly lively for the Blades.

A heavy touch by Jamie Vardy allows John Ruddy to run out and knock the ball clear.

If that had been even slightly better, the Foxes forward would've been in. Big let-off.

Brilliant through ball from Ben Osborn, a well-weighted pass with his left foot.

Osula took a touch, but sort of tripped over and Gus Hamer saw his shot blocked off. That's what the Blades need.

Sheffield United have not let their heads drop since going a goal down.

Gustavo Hamer has a shot blocked as they try to get back on level terms.

Luton started on top but Everton have managed to work their way into the contest.

A really even contest now.

Championship leaders Leicester are dominating possession, as you might expect, but it's Birmingham City who are racking up the attempts.

The Foxes are yet to land a shot on target after 20 minutes after Yunus Akgun misses.

Wonderful strike. What was disappointing there was the back four was so narrow and they've gone through.

It's gone through the midfield, he's rode a couple of challenges and it's gone straight past the keeper, there was nothing you can do.

You have to hit a wonder strike to score from there. It's disappointing for Sheffield United but it's early days, they've got to get into it.

It's pure technique from Facundo Buonanotte, it is effortless.

Amadou Onana grimaces as he returns to the pitch following that challenge. Sean Dyche will wait and see whether it's one his player can run off.

Reece Burke does brilliantly to get across to Amadou Onana, who sprints into the box to meet Dwight McNeil's perfectly weighted pass, but it leaves both players down in pain.

Onana is going to need a bit of attention here. Not what Sean Dyche wants to see after little over a quarter of an hour played.

Off the post, twice!

First Jaidon Anthony's strike hits the post and then Conor Hazard makes a great save to push Wilfried Gnonto's effort onto the cross bar.

A decent attempt by Koji Miyoshi as the visitors threaten at the King Power Stadium.

Picking up the ball to the right of the box, Miyoshi sets himself up for a curling shot with his left foot but it's just too high to concern Jakub Stolarczyk.

It's all happening now.

Oliver Norwood is given a yellow card but there's a VAR check to see if it should be more.

After a fairly swift decision, it remains as a yellow card.

A first real chance for Everton - and Beto very nearly makes it count!

It's well worked by the Toffees, who break forward quickly down the left before Beto receives the ball in the centre and guides a low shot narrowly wide with Tim Krul scrambling across his goal.

Great header from Evan Ferguson but it's disallowed for offside.
