Burnley midfielder Steven Defour is interesting Antwerp.
Defour is working his way back to full fitness from a serious calf injury.
And HLN says contact between the midfielder and Antwerp has been ongoing for some months.
Clarets boss Sean Dyche is prepared to allow Defour to leave following the arrival of Danny Drinkwater from Chelsea.
For the moment, Antwerp are yet to make contact with Burnley about a fee for the Belgium international.
