Derby County will play Aston Villa in the Championship play-off final on 27th May after beating Leeds United on an action-packed night at Elland Road.
Frank Lampard's side produced an exhilarating display in the second leg after losing the first match at home 1-0 and eventually won through 4-3 on aggregate.
It was certainly not plain-sailing for the Rams though as they fell a goal behind on the night and 2-0 down on aggregate on the before being handed a lifeline when Jack Marriott was introduced as a substitute just before half time.
He scored 33 seconds after coming on to the pitch and Derby netted twice more in the opening stages of the second half through Mason Mount and Harry Wilson's penalty to lead 3-2 on aggregate.
Leeds responded through Stuart Dallas' second goal of the second leg only for Marriott's late winner to confirm Derby's place at Wembley.
Lampard said: "Jack's been really good for us this season. I just felt in the last couple of months, in terms of what I really want from Jack, what can make him the player he was here, is the absolute ethic to do everything as an all-round striker.
"He's not the tallest. He's strong in terms of stockiness, but he needs to work without the ball, to have a hunger and desire constantly.
"It means such a great deal. To get into the play-offs after such a great run and to go 1-0 down and do something that no team has ever done in the play-offs after losing the first leg at home. In terms of personal achievement, the feeling is as much as I've had in football.
"It's not the personal achievement of being able to win stuff at Chelsea, but in terms of how I feel right now, it's up there."
Derby can be backed at 13/10 to be promoted to the Premier League this season while Villa are available at 8/13.
