Swiss champions Grasshopper-Club have parted company with coach Marcel Koller after five straight defeats.
The 43-year-old, who led Grasshoppers to the title last season, has been relieved of his duties after a 2-1 loss to lowly FC Wil 1900 left them in eighth place in the ten-team division - 26 points adrift of leaders FC Basel.
Reversal of fortunes
Former Grasshoppers midfield player Koller was a hero at the Hardturm stadium barely four months ago as his side surprisingly took the title from Basel, but after 12 games of the new campaign, his magic touch seemed to have eluded him. His last five matches in charge included 4-0 defeats by Basel and BSC Young Boys, a 3-1 reverse at Neuchâtel Xamax FC, a 3-2 loss to FC Aarau, and finally the 2-1 defeat by Wil.
Argentinian Carlos Bernegger, who was formerly Koller's assistant, has been named caretaker manager. Meanwhile, Grasshoppers' sporting director Mathias Walter has also left the club, with general manager Georges Perego taking over his position.
Grasshoppers are yet to reveal whether a new coach will be appointed before the second leg of their UEFA Cup first-round tie against Croatian side HNK Hajduk Split. Grasshoppers were held to a 1-1 draw in the home leg in Zurich.
