Leicester City must pay £1million if they want to prise Nigel Pearson away from Hull City, the Mercury understands.
Negotiations over Pearson's potential return to City have reached a stand-off over Hull's seven-figure compensation demands.
It is still believed Pearson will eventually return to the King Power Stadium after nearly 18 months with the Tigers.
But City will either have to agree to pay the figure, which includes the employment of Pearson's assistants Craig Shakespeare and Steve Walsh, or Hull's Egyptian owners must relent and accept a figure of around £675,000, which is believed to be what the Tigers paid for Pearson in June 2010.
The third option is for Pearson to resign and leave himself open to legal action for breach of contract, something he will be reluctant to do, and the 48-year-old will hope a compromise between the two clubs can be reached.
However, both sets of owners are powerful in the business world and are used to playing 'hard-ball', and it seems a case of which side will blink first.
Hull owner and chairman Assem Allam is a said to be a formidable businessman who has been stung by the prospect of losing Pearson, who has 20 months remaining on his Tigers contract.
Allam will not allow Pearson to depart without sending out an unequivocal message.
However, City's owners, Thai chairman Vichai Raksriaksorn and his son, vice-chairman Aiywatt Raksriaksorn, are also tough businessmen who have built the King Power empire in Asia.
While they have demonstrated they are willing to spend big to achieve their aim of getting City back into the Premier League, they have time and again made it known they will not be held to ransom.
A £1m figure for Pearson, on top of the pay-off that manager Sven-Goran Eriksson received when he left the club more than two weeks ago, could take the bill for the managerial change to around £2m.
As a result, Pearson's future has been left in limbo and the delay in his transition back to City is eating into his preparation time for the visit of Crystal Palace a week on Sunday, which is expected to be his first game in charge.
City had hoped to have their man in place before this weekend and get their promotion push back on course quickly, but it appears a final deal with Hull is far from complete.
