Skysports.com understands a host of clubs are chasing skilful Leeds midfielder Neil Kilkenny.
The Australian international is out of contract in the summer and as yet no new deal has been agreed at Elland Road.
The news has alerted a number of sides to Kilkenny's possible availablity for a bargain fee in January or on a free transfer next summer.
The likes of Queens Park Rangers, Middlesbrough, Derby and Sheffield United are all thought to be monitoring the talented midfielder's situation at Leeds.
The 24-year-old has established himself as a key member of Simon Grayson's squad since arriving in January 2008 and he played a key role in their promotion to the Championship last season.
However, Leeds could decide to cash-in on the former Birmingham man in January if they fail to agree a new contract with Kilkenny rather than risk losing him for nothing at the end of the season.
