The 20-year-old midfielder has recently been linked with the likes of Manchester United, Manchester City and Chelsea.
Reports on Friday suggested that Bruce had placed a £20million price tag on the England Under-21 star.
He said: “I haven’t put any price tag on anything. The only thing I know is that Jordan is an exceptional footballer and has got the world talking about him since he scored for the Under-21s in front of the England manager.
“The speculation that he is going to be in the next England squad has had everybody talking about Jordan.
“We have known about him for about 18 months now. He is a fantastic player.
“I haven’t put any price on his head at all, that would be ridiculous of me.”
