Hendrick has been a target for Burnley all summer with at least four bids being rejected by Derby for the 24-year-old.

But Dyche expects to finally complete the protracted move on deadline day after agreeing a fee with the Championship club.

Hendrick impressed at Euro 2016 for Martin O'Neill and started every game for Ireland in France.

Burnley's previous transfer record was the £8 million spent on Belgium international Steven Defour earlier this month.
