Hull City chairman Adam Pearson has admitted the wage bill at the KC Stadium must be reduced as soon as possible.
Pearson returned to the Tigers last month following a spell with Derby County and has already declared that any new signings in January are likely to be loan deals.
He has now suggested that the wage bill at the Premier League strugglers must be brought under control immediately if they are to avoid losing some of their key players.
"The priority is still very much on moving players on but that can be very difficult in January," Pearson told the Hull Daily Mail.
"We have to raise funds as a trading club but that's very much up in the air as we stand.
"There are no definitive offers in place for any of our players and that makes it difficult to plan for what may come in.
"In an ideal world we'd like the wage bill to be £5-6million lighter but that isn't straightforward."
