Skysports.com understands Leeds midfielder Neil Kilkenny is attracting interest from Hull City, Burnley, Nottingham Forest, Ipswich and Bristol City.
The Australia international is out of contract at Elland Road and has rejected a new offer from the Championship club.
A widespread number of Leeds' second division rivals are consequently paying attention and there is fierce competition for his signature.
Kilkenny played for Australia in their 3-0 win over New Zealand on Sunday and is set to feature in Tuesday's international against Serbia.
But the 25-year-old, who has spent time at Birmingham and Oldham in his career, will then make a decision on his future.
