Championship play-off semi-final: Derby fight back to beat Leeds - as it happened

So we have a mouth-watering final to look forward to on Monday, 27 May.

Aston Villa, beaten play-off finalists last year, will face Derby County for a place in the Premier League.

The Rams have experience of losing finals before, to Leicester in 1994 and QPR in 2014.

Can they end their 11-year absence from the top flight or will Villa end their three-year exile?

Ben Williams: Great match tonight in the play off semi-final. Well played Derby and best of luck in the final. As for Leeds if you start next season the way you've finished it you'll be lucky to stay up.

Ernest Monjol: Congrats to a legend super Frank Lampard, against the odds you did it. Next up is the richest game in world football. Can't wait to see you on the bench.

• Harry Wilson's 58th minute penalty means the Rams are 3-1 up on the night and ahead in the tie for the first time
• Four minutes later Stuart Dallas pulls a goal back for Leeds, making it 3-3 overall
• After Leeds defender Gaetano Berardi was sent off, Jack Marriott clips in his second of the night on 85 mins to put Derby 4-3 ahead on aggregate

Emma: Wow. That's what the play-offs should be! Awesome game, well done.

Geoff Kidd: You only need to beat @LUFC once a season for it to count! Fantastic effort @dcfcofficial

Craig Harper: 4-2 wasn't in the spy's report, was it @LUFC? These are the best @EFL play-offs in a long time!

This was the fourth meeting between the two sides this season, and the first time Derby have won after suffering three defeats in the previous matches. A good time to find their feet.

Quote Message: What a night. If we were going to do it, that is the way to do it. I was more nervous when we had a goal lead than I was before the game when I was quite calm. But towards the end I was on the edge. This is Frank's first season as manager and no-one has done this before. What an achievement. from Mel Morris Derby owner on BBC Radio Derby

Quote Message: It is a tough place to come and we did it. Everyone wrote us off and we showed desire. What a game to be a part of. You can see what it means to the fans. Now we are at Wembley and we go again. We are a confident bunch and we will go into the final just like we did today. from Jack Marriott Derby striker on Sky Sports

Quote Message: What a game. We knew coming into it that we would have to go for it. When they get the goal you think it might not be our night. Goals change game and the nature of our first unsettled them. We smelt it at half-time and anything can happen at football. Second half we were brilliant and I thought we were the better team. To come here and score four goals speaks for itself. But what a crazy night. We have really grown as the season has gone on and to win and give us an opportunity of getting to the Premier League... I am proud. from Richard Keogh Derby captain on Sky Sports

Quote Message: I said to the lads that everyone had written us off. We change the system and made a little tweak. But we needed the lads to show bravery on the ball and they did. The goal before half-time gave the players belief and I am so delighted for Jack Marriott. I felt it was his night but I didn't know he'd do that. We have to enjoy the moment but now prepare for Aston Villa, but we'll be underdogs again from Frank Lampard Derby County boss on Sky Sports

Quote Message: We felt we were on top at half-time and that they were losing confidence. We had a lot of belief coming into the second half and then we got an early goal. We were playing attacking football and pressing high. The message was to keep going. It is tough to come here and win, or even score a goal. But these games are different and it went our way. from Mason Mount Derby midfielder on Sky Sports

Everyone thought Leeds would roll Derby over tonight but Derby stood strong and there have been some manful performances.

It is absolutely stupendous. They have stood strong and have a great opportunity at Wembley now.

Derby continue their celebrations on the pitch.

Their players make their way towards the travelling support to dance and sing in front of their fans.

"Que sera sera, we're going to Wembley" rings out.

What a night.

From 2-0 down on aggregate, Derby fought back to progress thanks to Jack Marriott's late strike.

The Rams will face Aston Villa at Wembley on Monday, 27 May for a place in the Premier League.

Leeds will need to face up to another year away from the top flight.

Jack Clarke gets to the byline and his ball in is deflected into the arms of Kelle Roos. That'll be it surely.

Tom Lawrence pumps the ball into the Leeds right-back position and out for a throw.

Leeds need to get it forward and quick.

Tom Trewick: This Leeds v Derby game is one of the best games of football I've watched in a long time! For these young Derby players to have silenced a home Leeds crowd, on a night like this, after conceding first and then being pegged back, is something else...

Marvin Happe: I’m following this from my yacht just off Bermuda. I can’t believe what I’m reading. Great match, go on you Rams and super Frank Lampard!

Leeds work the ball into Izzy Brown in the Derby area.

He turns goalwards, then fouls a Rams defender.

Time is almost up.
