Erling Haaland's final destination this summer is set to become the major talking point of the transfer window and Borussia Dortmund will be desperate to keep hold of their star striker.
But the German giants have a habit of selling their best talents, and to their credit they often manage to fill the voids in a competent fashion.
So if Haaland does end up at Manchester City, Real Madrid or even Chelsea in a few months time, Dortmund's eagled eyed scouts will have already identified his replacement.
Early suggestions seem to indicate that the man to replace Haaland could be Sasa Kalajdzic - but who is he and does he have what it takes to fill such big shoes?
