Preston North End owner Trevor Hemmings has revealed it is costing him £750,000 a month to keep the League One club alive.
Hemmings says by the end of the season his investment will total £25million.
He told the Lancashire Evening Post: "I'm not looking for a buyer.
"We are trying to clean the club up in terms of finance.
"Apart from what is owed to me, the club's level of debt to the bank is manageable and fairly small in relative terms. I would like to see some of my investment back – if you put in £25m, it's reasonable to think that way.
"By June 2012, over a three-year period I'll have put in £25m to use on wages and running costs."
