Robbie Savage has thanked manager Nigel Clough after signing a new deal with Derby, while Jake Livermore's loan move from Tottenham has also been finalised.
The Welsh midfielder endured a difficult spell under previous boss Paul Jewell but Clough has helped to transform him into more of a creative playmaker.
He has now penned a contract extension that keeps him at Pride Park until 2011 and is excited about what the future holds for the club.
Savage is delighted to be staying and feels Clough can steer the Rams back to the Premier League.
"If you'd suggested to me eight months ago that I'd be signing a contract extension I'd have thought you were mad," he told he club's official website.
"But it's been an incredible turnaround and there is no one happier than me to have proved that I can still do a job for this great club.
"I can't thank the gaffer and his staff enough for what they have done for me; I love my football again and it's down to them.
"I've had to change the way I play. At 35 you can't run around like a mad man and expect to have the same impact on the game.
"I think we could be at the start of something special. This club should be in the Premier League and I believe under Nigel Clough and his staff we will get there."
Livermore has joined Derby on an initial one-month loan but Clough is keen to keep him until the end of 2009.
The 19-year-old midfielder is currently suspended and will not be available until the clash with Plymouth on 22nd August.
"He is a big, powerful energetic midfielder and someone who we believe can do an important job for us," said Clough.
"We want to keep him until Christmas at least and see how it works out for both parties."
