Although the former Charlton star is an alleged target for Liverpool and Arsenal, Leeds insist they have received no bids for the transfer-listed midfielder.
Elland Road boss David O'Leary has admitted he is hopeful of persuading his star to put pen-to-paper on a new contract, even though talks over a new deal collapsed.
Yet agent David Geiss claimed there would be no U-turn from his client, as he waits for any offers to arrive for the 25-year-old.
"His (Risdale's) attitude seems to have changed over the past six months," protested Bowyer.
"I can only guess why that is."
