Nottingham Forest manager Steve Cotterill says the club may have to buy new players before they sell to safeguard their Championship status.
Owner Nigel Doughty's decision to withhold funding beyond his current commitments means the Reds boss has no cash for new players.
Cotterill told BBC Radio Nottingham: "Sometimes we will have to spend money to get some players in.
"Then players can be looked at to see whether they are going to play."
Since Cotterill took over it has been widely reported that he would need players to leave his squad to free up cash to make new signings.
Forest were beaten 1-0 at home by Crystal Palace at the weekend and remain inside the Championship relegation zone.
The Reds have now lost four games in succession and are 22nd in the table behind Bristol City on goal difference.
"It is going to take us being flexible at the club. We are just unbalanced but that's my job. I have just got to somehow manoeuvre that around," added Cotterill.
"I think that is why I was given a three-and-a-half year contract and this is not going to happen overnight. I will do it but it is going to take time."
