Peterbrough's director of football Barry Fry has said Wolves can have Aaron McLean for no less than £5million.
The outspoken former Posh boss has told the Championship side to splash the cash if they want to secure the services of the highly-rated 25-year-old.
The 33-goal hitman helped United gain promotion to League One but McLean has made it no secret that he wants to leave the London Road club.
Wolverhampton Wanderers boss Mick McCarthy has turned his attentions to Darren Ferguson's main striker after missing out on Burnley's Kyle Lafferty to Rangers.
But with two offers from Wolves already turned down, Fry told the Express and Star: "I've told Mick McCarthy twice and Jez Moxey at the chairmen's meeting last week the price is £5million - £3million straight away plus a sell-on and £2million when you get to the Premier League, because if you get Aaron, that's where he'll take you.
"Mick says there's no way we'll get that, but that's the price. It doesn't matter that his best mate is Michael Kightly or he wants to play for Wolves, that's the price.
"We've had two bids from Wolves of £1million and £1.5million and turned them both down. I've heard they are preparing a third offer but we haven't heard anything.
"Steve Morgan has put £30million into the club - well then spend it, take a gamble."
Fry also said there was interest from another six clubs including Charlton, Sheffield United and Watford, but will not budge from the £5million price-tag.
"My chairman bought him to get us to the Championship.
"Aaron's a prolific goalscorer and if he gets us into the Championship, he'll be worth £7million, £8million, £9million," he added.
Meanwhile Swindon Town are set to make a bid within the next 48 hours for Wanderers' left-back Charlie Mulgrew according to the Swindon Advertiser.
But Town boss Maurice Malpas is remaining tight-lipped over the potential cash offer for the 22-year-old who had a loan spell at Southend last season.
