Birmingham City boss Lee Clark has reiterated that it would take 'a crazy transfer fee' to steal Jack Butland away from St Andrew's.
The 19-year-old goalkeeper has seen his profile rise considerably this summer, with a call-up to England's Euro 2012 squad placing him under the spotlight.
He is yet to make his senior debut for the Blues, but he is considered to be one of the hottest prospects in English football.
Stuart Pearce has noted that fact and has included Butland in his Team GB squad for the 2012 Olympics.
The likes of Southampton and Tottenham Hotspur have also been alerted to his potential, with the Saints reported to have seen one big-money approach knocked back.
Birmingham have no intention of parting with Butland and Clark has made it clear that it would take silly money to tempt the Blues into a sale.
"If other clubs want my players, I'm cool because it means they're good," he said.
"But it will take a crazy transfer fee for Jack to leave this club."
