Both arch-rivals Bayern Munich and Liverpool are among the teams that have been linked to Schlotterbeck, who is a key player for Dortmund.

In a recent interview, Kovac expressed his concerns about losing Schlotterbeck, stating that while he can show the player appreciation, he may not be able to influence his decision to leave.

Kovac emphasized that only time will tell whether Schlotterbeck will stay or go, adding that he is optimistic but cannot predict the future.

Dortmund is set to face Bayer Leverkusen in a Bundesliga match on Saturday, November 29, but the team's focus is likely to be on their upcoming game rather than Schlotterbeck's future.
