The German lost his job after Fleetwood were beaten 3-0 at Doncaster on Saturday.
Ex-Wigan Athletic boss Gary Caldwell is the favourite to become the new manager of the club, but he has been out of a job since September after he was sacked by The Latics.
If Caldwell takes charge he would have to accept Fleetwood’s club structure, which means he will be head coach under the director of football, Gretar Steinsson, instead of manager.
The Fylde coast side have not won at home in the league since October and their last victory came away at Southend United on January 13. Town have suffered seven defeats in a row in all competitions dating back to that win at Roots Hall.
Fleetwood are currently outside the relegation zone but only due to goal difference. The demise over the past six weeks has also led to a fall in ticket sales which has affected the club as well.

Current development manager and former Fleetwood player Barry Nicholson has been appointed caretaker boss for tomorrow’s clash with Pompey at Highbury.
On the management situation at Fleetwood, Andy Moore, from the Blackpool Gazette, said: “If the caretaker boss Nicholson can get a result, he has every chance of staying for the rest of the season.”
Former Bradford City manager Stuart McCall is also in the running for the vacancy.
And there’s speculation involving rivals Blackpool. The rumours are of a manager swap, with Seasiders boss Gary Bowyer heading to Fleetwood and Rosler taking his place at Bloomfield Road.
