Patrick Bamford wins a free-kick after the referee played a good advantage following a lunge from Bradley Johnson and a shirt-pull from Jayden Bogle.

A chance to get the ball into the box.

Bresla Stephenson: Chelsea fans here rooting for Super Frank Lampard. But would be good to see Leeds back up and also John Terry's Villa.

Sulaimon Adelekan: One part of me wants Frank Lampard back in the Premier League if they beat Aston Villa but another wants Marcelo Bielsa 'el loco' just for the drama. Any of the teams will give us a fantastic play-off final.

Jim Harper: Villa fan so lots of injuries and red cards please. Only joking. Wink, wink.

That is now 11 yellow cards so far across the two legs.

Four Derby players were booked on Saturday, and three have cautions tonight.

I'm not sure we are going to finish with 11 vs 11 here.

It's got feisty.

Rams left-back Scott Malone shoves over Pablo Hernandez when the Spaniard is trying to take a quick throw-in on the right. That's a booking.

Tom Lawrence comes in and gives Anthony Taylor some stick, so gets booked for dissent.

Then Hernandez puts his head into Malone's midriff as he gets back to his feet. So he gets a yellow too.

Antony Taylor now has a word with Derby's Mason Mount and Leeds' Stuart Dallas after a slight follow-through from the Rams man caught the Irishman.

Jack Harrison gets a talking to from the ref after stepping on the foot of right-back Jayden Bogle after the ball had gone.

Derby are matching Leeds in every department at the moment but can they sustain it?

Derby work their way forward and then Mason Bennett sends a great low cross fizzing around goal from the left wing.

There is no-one in a dark purple shirt to get on the end of it and Leeds smuggle the ball clear before winning a free-kick for a foul on Stuart Dallas.

Leeds carve out their first opportunity.

Luke Ayling starts it and the ball is worked to Mateusz Klich on the right.

The midfielder clips the ball into box and Ayling is there, having carried on his run.

The right-back attempts an ambitious hinch-kick volley which goes well over.

Leeds enjoy their first period of settled possession as they look to take the sting out of Derby's start.

They have weathered the early Rams storm.

Leeds finally get the ball in the Derby half and look to play a quick through ball, but Patrick Bamford is on his heels.

They try again and Jack Harrison flicks the ball around the corner - but Bamford is flagged offside.

Jayden Bogle comes down the Derby right and wins another corner for his side.

Leeds skipper Liam Cooper beats Richard Keogh to the ball at the back post.

Derby are pinging it around well at the moment.

A ball was pumped long to Patrick Bamford just now and the Leeds striker couldn't make it stick.

The Rams are on top in the early stages.

Derby have done more in the first seven or eight minutes tonight than in the whole of the game on Saturday.

They're showing a will to get the ball back and look a different outfit.

Mason Bennett makes a nuisance of himself in the Leeds box and eventually gives away a free-kick for his hassling of a defender.

Derby have been on it from the start, and look completely different to the side from Saturday.

It suits the right-footer, and Mason Mount's effort goes behind off the Leeds wall.

Leeds deal with the corner, but the Rams then win a throw-in.

Jay Rumball: Hoping for a Derby miracle tonight, Chelsea fan so always backing super Frank! C'mon the Rams, 3-1.

James H: As a Villa fan I would prefer Derby, but I honestly don't see Leeds falling at home. It would be an entertaining final at Wembley if Leeds meet us there.

Sriaght up the other end and a mix-up in the Leeds defence presents the Rams with an opening.

Kiko Casilla comes out of his area and makes a hash of his clearance.

It goes straight to Harry WIlson, and his rushed effort is off target.

He was fouled while shooting now, and now Derby have a free-kick on the edge of the area.

Derby don't clear the first ball and it drops to Luke Ayling, but his effort goes high and is claimed by Kelle Roos.

Patrick Bamford gets on the end of a ball forward on the right and bursts infield towards goal.

He goes down just before getting to the box and Derby centre-back Fikayo Tomori gets a caution. This is in a great position for the Whites.
