Frank Lampard said he made a slight tactical adjustment as Derby County came back to beat Leeds United 4-2 to go to the final of the Championship playoff.

They will play Aston Villa in the final.

Derby were down 1-0 heading into the second leg.

"I said to the lads that everyone had written us off. We changed the system and made a little tweak. But we needed the lads to show bravery on the ball and they did. The goal before halftime 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."

The matchup pits Lampard against his former Chelsea teammate John Terry, an assistant manager with Villa.
