Sacked Norwich City manager Daniel Farke is being linked with Werder Bremen.
Werder are seeking a quick appointment after the resignation of Markus Anfang.
The German Second Division outfit are eager to find a "quick solution", according to sporting director Frank Baumann.
Farke is being mentioned as a candidate, as is Apollon Limassol's Alexander Zorniger.
For the moment, Danijel Zenkovic (34) is in charge of Werder as caretaker coach.
