DERBY County are making no official comment about a report that they have complained to the Football League over an unpaid £85,000 bill from rivals Nottingham Forest.
The Daily Telegraph has reported that the two clubs are rowing over a payment related to ticket money from their meeting at the iPro Stadium last month.
Derby are said to have written a letter to the League and demanded action be taken.
They allege that Forest missed a seven-day deadline to repay the outstanding amount last week and have been un-cooperative on the matter.
On a routine basis, Championship clubs reconcile the monies from seats sold to their supporters at away grounds within a week after the game.
