Derby midfielder George Thorne has said that he is still unable to talk to Harry Redknapp about their 2014 play-off final defeat against QPR, despite the ex-Rangers boss now working for Derby.
QPR won the final 1-0 at Wembley and earned promotion to the Premier League.
Seven Derby players who played in that final are part of the squad which has already secured a place in this season’s play-offs.
“We don’t talk about it too much because it is a bitter memory for us,” Thorne told BBC East Midlands.
“He said to me that he thought I played well at Wembley, but I didn’t want to continue the conversation.”
Since Redknapp joined Derby as a football advisor in March, the Rams have won five of their six games.
And Thorne said the Rams, who finished outside the top six last season, feel as if they have “unfinished business at Wembley”.
Tuesday’s victory over Bristol City, took their winning run to four games and confirmed their play-off place with three games left.
Two of their remaining matches are against potential play-off opponents as they host sixth-placed Sheffield Wednesday on Saturday before travelling to Brighton next week.
“The three games now are about building momentum and maintain the winning streak that we have got going,” Thorne added.
“Two years ago we took a lot of momentum into the semi-finals and I do believe that was a help to us.
