The Whites recently tabled a new contract offer to the 25-year-old Australia international who is out of contract at Elland Road this off-season.

But the club have confirmed Kilkenny nor his agent have accepted the deal and Leeds boss Simon Grayson is now keen to move on.

"This is another issue we wanted resolving as we have to prepare for next season," Grayson told the club's website.

"I'm keen to move on so we can plan accordingly in terms of what we have and what we need."

The former Arsenal junior joined Leeds from Birmingham City in 2008 making 144 appearances for the Whites.
