RB Leipzig chief Markus Krösche cannot rule out selling Dayot Upamecano this summer.
A target for Arsenal, it's been suggested by Upamecano's agent that he may not move.
However, Krösche admits the defender will be sold if he refuses to extend his current deal. The Frenchman is tied to RBL to 2022.
"Dayot Upamecano is with us," he said.
"But of course there must be economic conditions and our goal is not that players leave us free of charge - least of all such top performers."
