Carlisle manager Greg Abbott is ready to ensure that the club receive a good price if star striker Gary Madine is to move on.
The 20-year-old hotshot has been linked with a series of npower Championship clubs but United are yet to receive an offer.
Madine is being monitored by Burnley, Norwich, Sheffield United, as well as several Premier League clubs.
"I would be staggered if there wasn't interest in Gary," Abbott told the News & Star. "We have got to prepare ourselves for a bid.
"He is the youngest centre-forward leading the line in this division, has scored 13 goals and is playing very well.
"I am not going to drum up any advertisements that he is for sale because he isn't. But in a way, everyone is for sale."
