The Rams head coach is worried that he may not be able to "field a team" for the start of the new season if the club fail to recruit fresh blood
Wayne Rooney has vowed not to quit as Derby boss, but the former Manchester United star has also called for new signings ahead of the 2021-22 campaign.
Derby were placed under a transfer embargo after being found guilty of breaching financial fair play rules last month, but the English Football League (EFL) has since softened its stance due to a significant shortage of registered senior players at Pride Park.
The Rams are now free to sign up to five players on free transfers or on loan, and Rooney has urged the club to get moving in the transfer market as he continues to try and populate his threadbare squad with academy graduates and trialists.
