Aston Villa boss David O'Leary has been told by chairman Doug Ellis that he will have to sell players to raise funds for new arrivals in the summer.
O'Leary's side have struggled for form this season
O'Leary is keen to make at least three signings along with turning James Milner's loan into a permanent switch.
"I've already been told by the chairman that to get players in next season it is what we sell that will enable us to buy," said O'Leary.
"We have to generate funds by what we can sell."
He added: "If we don't we will be staying with what we have got."
Villa need a point to secure their Premiership status and the prospect of any new signings will have to be put on hold at least until top-flight football is guaranteed for next season.
O'Leary added: "I can't plan ahead because the way the club is at the moment, we've just got to get it to the finish and then see what is going to happen."
