Cardiff City chairman Peter Ridsdale has reiterated that the club will only sell defender Glenn Loovens for the right price.
Loovens has been tipped to leave Ninian Park this summer with SPL clubs Rangers and Celtic both reportedly keen to secure his services.
The Bluebirds have received offers for the 24-year-old Dutchman, however the club's valuation of the player has yet to be met.
Ridsdale explained he would be willing to sanction the sale of Loovens as the player is out of contract at the end of the season, but is waiting to receive an adequate bid.
"We have had bids from two clubs for Glenn Loovens," Ridsdale told the South Wales Echo.
"Neither meet our valuation and both have been turned down.
"It is likely we will sell if the clubs involved meet our valuation - and (manager) Dave Jones would have money available to find a replacement."
He added: "We are intent on earning promotion to the Premier League and that means keeping our best players.
"None of those on long-term contracts are available - at any price.
"Glenn Loovens is a different case because he has not signed the new contract offered him. We have talked to him about that and said we are happy for him to stay through this season.
"But that would mean he could walk away next summer for nothing.
"If there is a bid which reaches a level we believe is fair then it is likely we would accept."
