Derby are expected to appoint Chris Hutchings as assistant manager to replace Stan Ternent, who is set to become Huddersfield's manager.
BBC Radio Derby understands that Rams boss Paul Jewell wants to renew working with Hutchings, his number two at Wigan less than a year ago.
Hutchings took the helm at the Latics when Jewell resigned in May 2007, but he was sacked in November.
Derby have yet to officially confirm Hutchings as Ternent's replacement.
But chairman of football Adam Pearson told the club's official website: "We already have a new assistant lined up and ready to start work.
"I am very excited about the future of the coaching staff moving forward, as is Paul Jewell.
"The new assistant has a proven pedigree and a top-class record and is someone well known to Paul.
"I would like to thank Stan Ternent for the hard work he has put in for Derby and the support he has given Paul."
Championship here we come
Hutchings, 50, was also Jewell's assistant at Bradford and helped guide the club to the Premiership in 1999.
Bradford then endured a difficult season in the top flight, but avoided relegation on the final day as they beat Liverpool 1-0 at home.
Jewell then left Bradford and Hutchings stepped up to take the reins, but lasted for only 21 competitive games before being sacked in November 2000.Hutchings was then reunited with Jewell at Wigan in 2001.
