Birmingham City boss Lee Clark has insisted that young goalkeeper Jack Butland will not be allowed to leave the club unless a "crazy transfer fee" is received.
The 19-year-old has attracted a host of European interest following his performances at youth level, while he has also claimed a place in the Great Britain Olympics squad for this summer.
"If other clubs want my players, I'm cool because it means they're good. But it will take a crazy transfer fee for Jack to leave this club," Clark told reporters.
Southampton and Tottenham Hotspur have both been credited with an interest.
