Nuri Sahin and Serdar Tasci are both on Trabzonspor radar, the Turkish Super Lig side have moved to confirm.
Both players were born in Germany to Turkish parents, and would probably consider moving to Turkey if an opportunity arises.
Trabzonspor chairman Muharrem Usta has moved to confirm his interest in Nuri Sahin and Serdar Tasci, who could be moving to Super Lig in the January transfer window.
Nuri Sahin has been going through a very rough patch of late and he has seen no action at Borussia Dortmund this season.
Having failed to make a single appearance for the Millionaires this term, the Turkey international is almost certain to leave Signal-Iduna Park for greener pastures in the winter.
Meanwhile, Serdar Tasci returned to Spartak Moscow after a largely unsuccessful loan spell at Bayern Munich, and he, too, would probably seriously consider an offer from Turkish Super Lig giants Trabzonspor this winter.
