Leicester City goalkeeper Ron-Robert Zieler is being linked with a return to Germany.
Bayer Leverkusen, VfL Wolfsburg and Hamburg are all keeping tabs on Zieler's situation after a difficult first season with the Foxes.
Zieler said: "Of course, I can imagine a return to Germany. But when that will be, I do not know.
"Actually, I really only concentrate on Leicester. When I'm needed in this important phase, I want to be ready - physically and mentally.
"I could not forgive myself for anything else."
