Manchester United great Wayne Rooney is enduring a tense relationship with Derby owner Mel Morris.
The Daily Mail says Rooney's relationship with Morris has become strained following the collapse of the proposed takeover by Sheik Khaled earlier this month.
The former England captain had received repeated assurances that the sale of the club would go through before he took the manager's job.
The uncertainty surrounding the club's ownership has added to Rooney's problems as he battles to keep Derby in the Championship, with four players sold to raise funds during the January transfer window and more likely to leave in the summer if Morris remains in charge.
Rooney has also had to contend with players' grievances at not being paid on time on several occasions this season.
