Chairman Adam Pearson wants as many as nine players to leave cash-strapped Hull but admits some are "reluctant" to move on.
Pearson is hoping to trim around £9million from City's annual wage bill to prevent the club plunging into serious financial difficulty. This month's transfer window provides a good opportunity to offload a number of fringe players but Pearson concedes that is easier said than done.
Pearson told the club's website, www.hullcityafc.net: "I would like to know we are going to get some players out, but even when we have found players moves over the last few days, they have been reluctant to leave."
He added: "They enjoy being at Hull City, their deals and packages are obviously good.
"We will continue to work on them and hopefully one or two will see the opportunities there for them and decide.
"We are working hard to move players out because we do do have probably six to nine players too many."
Hull were virtually debt-free when they won promotion to the top flight in 2008 but their spending since, in attempting to compete in the Barclays Premier League, has been damaging.
Pearson was brought in by the club's owners in October in an attempt to arrest the situation.
He added: "The club is significantly overpaying on its wage bill and has been significantly overpaying on agents' fees in the past year with big bills still to pay.
"We still have £2.5million in agents' fees to find and the club just can't afford that. We need to move players out and get the wage bill down because if we don't we are into difficulties and that is not what anybody wants for this club."
