The Germans are ready to pay €27m for Reine-Adelaide, 22, with Lyon in line to receive a percentage of any future transfer fee.
However, Reine-Adelaide has yet to agree to this move and is taking time to think about it.
Although he has said he wants to leave Lyon for more game time, it isn’t ruled out that he could stay.
The central midfielder went public with his unhappiness recently.
“It is difficult to imagine my future at Lyon,” Reine-Adelaide told RMC. “Today, I need to play matches consistently.
“I hear that I need to wait for exits in order to get a starting spot. But that is not the project that was sold to me when I came last summer.”
