The Rams only replaced Steve McClaren with Paul Clement last summer, but the former Paris Saint-Germain and Real Madrid coast lasted less than eight months in the job before being sacked earlier this month.
Former youth coach Darren Wassall is in charge until the end of the season, and Derby are bound to review the situation in the summer as they ponder a new appointment.
Now, The Scottish Sun report that Derby are keen to appoint Rangers manager Mark Warburton as their next boss, having impressed since turning to management.
Bizarrely, Brentford then chose to move on from Warburton, leaving the 53-year-old to head up to Scotland with Rangers - and his superb record has continued at Ibrox.
The Gers sit eight points clear at the top of the Scottish Championship table, and look set to win promotion back to the top tier of Scottish football with Warburton at the helm.
However, it's now suggested that Derby have held a long-term interest in Warburton, and are keen to lure him back to English football at the end of the season, with Rangers allegedly concerned that Derby may turn his head this summer.
