Former Tottenham boss Christian Gross has been sacked as head coach of Schalke.
Gross had only been in charge at the Bundesliga club for two months and was dismissed along with three other senior club staff.
Schalke are bottom of the German top flight and nine points from safety with 11 matches remaining.
His last match in charge was a 5-1 defeat at Stuttgart on Saturday.

Gross, 66, was Schalke's fourth coach of a turbulent season.
The first managerial casualty of the campaign was former Huddersfield boss David Wagner, who was sacked after his side conceded 11 goals in their opening two games of the campaign.
They were thrashed 8-0 by last season's champions Bayern Munich and then suffered a 3-1 loss against Werder Bremen.
