Derby County chairman Peter Gadsby insists they do not need to cash in on Giles Barnes.
Barnes has repeatedly been linked with Tottenham and West Ham, but Gadsby said: "The situation with Giles Barnes is that he is a very important part of this club.
"My advice to him would be to stay here and get his head down and take advantage of playing under a manager in Billy Davies who has an excellent track record of bringing on young players.
"We had an approach that we didn't want and the offer was unacceptable. We will be monitoring the Giles Barnes situation closely.
"This club has a history of being pillaged but interested clubs would be mistaken to think that Derby County is a soft touch. We are not a club that needs to sell, we are interested in progressing."
