Alan Pardew fears Newcastle United 'will have a problem' if clubs bid for midfielder Cheick Tiote at the end of the season.
Tiote has impressed at St James' Park since joining the Magpies from FC Twente last summer and has already been linked with rival Premier League teams.
Newcastle cashed in on home-grown product Andy Carroll on deadline day after selling the striker to Liverpool for £35million and owner Mike Ashley is keen to put the club on a sound financial footing.
Pardew understands the philosophy of Ashley and Derek Llambias and is hoping he can hang on to Tiote in the long term.
"I am hoping there are no bids, otherwise we will have a problem," said Pardew.
"Tiote is a very important player, very talented and someone we want to be a big part of our future."
He added: "When I became manager, they (Ashley and Llambias) made me aware that they wanted to get the club on a financial footing, which gives them a chance to build it.
"Signing young players and hoping they become successful in the Premier League is part of the policy of growing as a club.
"Now, ideally, you would like to keep someone like Andy Carroll, a young player who is from the area, but financially we could not keep him.
"But we like to think, certainly I have that ambition, that in two or three years' time, if we can sustain our status and keep getting the TV money invested wisely, that we can hold off that next bid which might be for Cheick in 18 months' time or so.
"We have to get ourselves in a position to do that because at the moment we're not and we have to accept that."
