Frank Lampard was honest when he was asked whether it was extra sweet that it was Leeds who Derby had beat to reach the Championship play-off final at Wembley.
'I'm not gonna lie because it is,' Lampard said. 'I heard a lot of people saying that we were crying about Spygate.
'I haven't thought about Spygate for a long time and we played them and we prepared for it, we prepared and we got a result.'
Leeds supporters spent much of the second half at Pride Park in the first leg singing a new chant to Oasis track Stop Crying Your Heart Out
, which included the lines, 'All of our spies are hidden away… Stop crying Frank Lampard'.
But on Wednesday night at Elland Road, Lampard was left smiling having watched his side overturn a 1-0 first-leg deficit to win the tie 4-3 on aggregate. Indeed, his players even sung the song in the dressing room after the match.
It was a sensational night in Yorkshire and after 24 minutes Leeds - already favourites to meet Aston Villa in the play-off final on May 27 - took the lead on the night when Stuart Dallas scored.

Lampard brought on Jack Marriott for Duane Holmes shortly before half-time and it proves to be an inspired move.
But it was through stupidity that Derby profited. Leeds defender Liam Cooper went to win the ball as it trickled into the home penalty area but goalkeeper Casilla didn't get out of the way forcing his team-mate to go to ground.
In doing so, Cooper played the ball into space to give Marriott the simplest of chances, which he took.
Derby took the lead on the night and levelled the tie when Mason Mount scored just a minute into the second half. Harry Wilson then struck from the penalty spot to put Derby ahead.
There was still more drama, though. Dallas scored with 28 minutes to play after he cut in from the left and shot into the bottom corner of Kelle Roos's goal.
But in the 85th minute, Marriott scored his second of the night to win the game. Mount played a quick pass to Richard Keogh, who saw Marriott making a run and played him through to the Leeds area. Marriott took a look up and dinked the ball over Casilla.
It came either side of Gaetano Berardi's sending off for Leeds and Scott Malone's dismissal for Derby.
'We were 1-0 down, I said to the lads everyone had written us off,' Lampard told Sky Sports after the match.
'It's 1/8 for them to go through or something, everyone says they've beaten us three times, but we made a little tweak, and it worked brilliantly but you need bravery on the ball and the lads showed it.'
The former Chelsea and England player said his players had worked hard to earn their chance to play at Wembley for a place in the Premier League.
He added: 'The workrate through the year, players coming in, we're not there yet, I watched Villa do this, but the players deserve it. The performance tonight, we were the better team over two legs, we should have had a penalty, but it was a brilliant performance from the lads.
'There's work to do, this isn't the end, we're underdogs again and we'll have a tough game against a brilliant Villa team, but we're there.'
Mount, who is on loan from Chelsea and has been one of the players of the season in the Championship this season, said Marriott's goal just before half-time gave them belief.
He said: 'The goal gave us loads of belief going into the second half, that helped. And getting an early one in the second half helped too, we played attacking football and pressed them high and got the goals.
'The message at half-time was to keep going - we were on top, we felt they were losing confidence, and when we came out for the second half we wanted to pounce on that and we did.'
