Sheffield Wednesday's owner has informed the fans they must pay out of their own pockets to save the club.
Thai businessman Dejphon Chansiri has attacked the club's fans by saying they are too negative.
Wednesday are in registration embargo for non-payment to HMRC last week.
They did, however, win their first game of the season on Sunday against Rotherham under new manager Danny Rohl.
Chansiri told the Sheffield Star: "With HMRC, if we don't pay until, say, the fifth of November, then that means it's been 14 days, but if we don't pay wages as well then that's five days - that means a total of 19 days. Each issue counts separately.
“If 20,000 people gave £100 then it's £2m, and it'd be clear - so we can finish it. That would cover everything, HMRC and the wages. That would need to be done before November 10th if they don't want to pass the 30 days, but that means that there can be no next time.
"It'd need to be before to make it safe - if it was on the fifth then there would be 10 days left… if we were to hit 30 days then we'll get a ban for three windows."
