Frank Lampard revealed that he was confident in Jack Marriott making the difference in Derby County's thrilling SkyBet Championship playoff semifinal victory over at Leeds.
Marriott hauled his side level at 1-1 on the night 33 seconds after stepping off the substitutes' bench shortly before half-time.
Derby, however, had luck on their side when they bounced back in the second half through Mason Mount and Harry Wilson's penalty.
Leeds returned the favour when Stuart Dallas scored his second goal of the night which took it to 3-3 on aggregate but Marriott made the difference to send Derby to the final at Wembley.
"The Jack Marriott one is a question I get asked. I know the fans want to see him playing," said Lampard.
"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 tonight, 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.
"I said to him before the game I had a feeling. I said I know you're upset, but I have a feeling that something's going to come from you today."
Lampard further added that his emotions were beyond him, nothing matched what he felt during his days as a footballer.
"It means such a great deal," Lampard said. "To get into the playoffs after such a great run and to go 1-0 down and do something that no team has ever done in the playoffs 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."
