Derby County say that Jeff Hendrick is not for sale despite reported interest from several Premier League clubs.
The Championship side are understood to have rejected a £3 million bid for the Irish international from Burnley.
Newly promoted Hull City are also believed to be keeping tabs on the 24-year-old following his impressive performances at Euro 2016.

Hendrick has two years left on his current deal at Derby.
