The 30-year-old, who is valued at £1.5 million, had an 18-month stint with Leeds in 2005 and manager Simon Grayson is reportedly keen to bring the striker back to Elland Road.
Derby’s first team coach Gary Crosby has said that the club could look to sell the striker this summer, and despite interest from Middlesbrough and Burnley, Hulse is thought to favour a return to Leeds.
"As much as we'd like to keep Rob, financially we will maybe look to sell him," Crosby told the Derby Telegraph.
"You do hear various things but it is only talk at the moment. There is nothing definite.
"Other clubs will be active in the market and most clubs want a striker who is going to get you goals."
