It looks like Derby have Tom Lawrence and Mason Bennett playing together up front, with a diamond in midfield.

The pair have 11 goals between them this season - Lawrence with eight of them.

A bit of head tennis and a bit of a tussle in the Leeds half, and the hosts get a free-kick for a shove by Tom Lawrence.

Elliott Stockdale: I’m a Forest fan supporting Leeds which feels weird. WE ALL LOVE LEEDS!

The hosts get us under way at Elland Road.

Leeds are in all white, with the Rams in their dark purple change strip.

Derby need a goal if they are to reach Wembley and keep their hopes of a place in the Premier League alive.

For Leeds, a draw will do.

Leeds United have handed out 30,000 scarves inscribed with "We are Leeds" to home fans.

Held aloft as the supporters sing Marching On Together, it's quite a sight.

Derby sold out their allocation of 2,670.

Elland Road is packed to the rafters.

Both sides are out on the pitch and kick-off is almost upon us.

As you'd imagine it is absolutely bouncing in here tonight with both fans already in fine voice.

This is probably Leeds' biggest game here since they clinched promotion back to the Championship with a dramatic final day win over Bristol Rovers in 2010.

It's been a long 15 years outside the top flight for the hosts. They're in the driver's seat to play Aston Villa in the final now but don't count Derby out just yet.

Can the Rams pull off a comeback or will Leeds be reaching Wembley?

Some seriously nervy fans at Leeds Utd v Derby County tonight - on both sides. But the visitors really are here more in hope than expectation.

Derby County will make history if they overturn the 1-0 deficit from Pride Park.

None of the previous 17 teams who have lost the first leg of a second-tier play-off semi-final at home have progressed to the final.

The Rams will need to be more proactive if they are to book a date in north London.

They did not have a shot on target against the Whites on Saturday, and only had two efforts in the second half.

Leeds keeper Kiko Casilla had so little to do he could have been holding an ice cream cone for the whole game and barely damaged the wafer.

Both sides have had big-name backing on social media in the build-up to kick-off.

Former Leeds and South Africa captain Lucas Radebe has tweeted his support...

While former One Direction star Niall Horan has given encouragement to the Rams.

Apparently he has a solo career, too.

Both these clubs have endured their fair share of play-off heartbreak in the past.

Derby are taking part in the end-of-season jamboree at this level for a record-equalling eighth time.

The Rams have been promoted just once from their previous seven outings - in 2006-07 after beating West Brom.

County have lost two other finals, to Leicester in 1994 and QPR in 2014, and were beaten semi-finalists last season, losing to Fulham.

Leeds, meanwhile, have never been promoted via their previous four appearances in the play-offs.

The Whites were beaten in the Championship play-off final by Watford in 2006 - with Kevin Blackwell in the dugout at Cardiff's Millennium Stadium that day - and by Doncaster in the League One final two years later.

One club will have another story of despair to add to the annals come full-time tonight.

Saturday's first leg got a bit feisty towards the end, with four Derby players picking up yellow cards - to Leeds' three.

Remember, there is some needle between the two clubs following the 'spygate' saga in January, for which Leeds were fined £200,000 by the EFL.

Derby midfielder Tom Huddlestone was cautioned after appearing to strike Stuart Dallas with his arm late on at Pride Park, and Derby boss Frank Lampard wants his players to keep their cool tonight.

"We all know the intensity of this game - it's big between the clubs and that ramped up in January for obvious reasons," the former England international said.

"I'm not worried about their players, I'm worried about mine.

"What they must do is give everything and not overstep the line by doing anything that could get them sent off by putting their head into someone or doing something petulant in the game.

"Those are the things we need to stay way from, but other than that give everything."

Leeds have have never beaten a side four times in a single season and need just a draw to go through to Wembley.

The Whites have been away from the top flight for 15 years, and lost a Championship play-off final to Watford 13 years ago.

Head coach Marcelo Bielsa is expecting a difficult encounter at Elland Road as Derby try and get back into the tie.

"It's two games, but we could say it's just one game and we've just played the first half," the Argentine said.

“The difference is only one goal and the idea is to increase the difference and prevent the opponent from reducing it.

"Usually you don't make comments at half-time and usually you work to build a superiority in the time that you have to play.

"The first game was not simple for us, and we're sure that the next game won't be easy either."

Leeds' win over Derby on Saturday was one of the more comprehensive 1-0 wins you'll see. The Whites have now beaten the Rams in all three of their meetings this season, with an aggregate score of 7-1.

I think most people think this is theirs to lose now but anyone with even a passing knowledge of the Elland Road side's recent history knows that this is a club that very rarely do things the straightforward way.

One man who is full of confidence is BBC Radio Leeds' United summariser Noel Whelan, who said: "I don't think they can stop us. We're a better side."

Ahead of the first leg of this play-off tie the soccer boffins at the Euro Club Index, external calculated that Derby were the favourites to reach Wembley.

They gave the Rams a 58.5% chance of coming out on top, with a 28.0% chance of sealing a place in the top flight.

The figures, meanwhile, gave Leeds a 17.2% hope of returning to the Premier League.

Well, Kemar Roofe's goal has changed all that and they've got the calculators back out.

With the tie poised as it is, now the odds are in Leeds United's favour.

The Whites have a 77.4% chance of a place in the final, and a 33.3% shot at sealing for promotion.

For Derby, it's now just a 10.6% shot at a place in the top flight.

Tonight's winners will face Aston Villa at Wembley on Monday, 27 May after Dean Smith's side overcame West Bromwich Albion on penalties last night.

Craig Dawson's first-half header meant the Baggies took the tie to spot-kicks, where Villa keeper Jed Steer was the hero, saving twice.

Villa were beaten in the play-off final by Fulham last year, so have experience of the big occasion.

Derby County boss Frank Lampard makes one change from Saturday's first leg defeat at Pride Park.

Derby XI: Roos, Bogle, Tomori, Keogh (capt), Malone, Holmes, Johnson, Wilson, Mount, Lawrence, Bennett.

Patrick Bamford returns up front for Leeds after serving a two-match ban as head coach Marcelo Beisla is forced into two changes from their first-leg victory.

Kemar Roofe, who scored the only goal of the first leg, has suffered a calf injury, while Adam Forshaw misses the game with a knock.

Jamie Shackleton replaces Forshaw in the Whites midfield.

Influential centre-back Pontus Jansson is back on the bench after an ankle problem.

Leeds XI: Casilla, Ayling, Berardi, Cooper (capt), Dallas, Phillips, Klich, Hernandez, Shackleton, Harrison, Bamford.

Subs: Peacock-Farrell (GK), Struijk, Jansson, Gotts, Bogusz, Clarke, Brown.

• Craig Pawson awarded the Rams a penalty with 14 minutes to go, after Jack Harrison tangled with Jayden Bogle
• After speaking to his assistant, Pawson then reversed the decision and gave Leeds a free-kick instead

If you want more info, then read Brent Pilnick's report so you're fully up to speed before kick-off.

Just four days after their first clash at Pride Park, Leeds United and Derby County reconvene for the second leg of their Championship play-off semi-final.

The Whites hold a 1-0 aggregate lead, and are aiming to beat Derby for a fourth time this season.

Both clubs are desperate to reach Wembley and keep their hopes of reaching the Premier League alive.

Leeds have been away from the top flight for 15 years and Derby have been absent for 11 seasons.

Only one can progress. For the other, the exile will continue.
