Leeds United face competition for Club Brugge left-back Laurens De Bock and have not yet agreed a fee with the Belgian side for the 25-year-old's services.
De Bock wants to quit Club Brugge in this month's transfer window and has already agreed in principle a contract running for four-and-a-half years with Leeds.
But there is not yet any agreement between Leeds and Club Brugge.
And according to Belgian daily Het Nieuwsblad, De Bock is also attracting interest from clubs in Germany and Italy.
Club Brugge, knowing De Bock is a wanted man, will want to make sure they sell for the best possible fee.
