Dean Windass is unhappy that Bradford have revised their valuation of him for a permanent deal.
The veteran striker told the Hull Daily Mail: "I will be very disappointed if nothing comes around now.
"It (the hold up in completing the move) is just the transfer fee. It's not about the money for me; it's the money for the two clubs.
"I spoke to Julian Rhodes (the club chairman) and he said he would not stand in my way and all of a sudden Stuart McCall has got the job and the goalposts have moved."
