Schalke 04 have sacked their coach Huub Stevens, following a run of six games without a win in the Bundesliga.
Jens Keller has been placed in charge of the side for the rest of the campaign.
Chairman Clemens Tonnies told Sport1 Television: "We are definitely planning with Jens Keller until the end of the season.
"We had to react. Huub Stevens is a great guy and he sacrificed his personal interests for the good of the team.
"I don't know exactly what has happened, but after the Leverkusen game, some kind of change took place."
The final straw was a 3-1 loss to Freiburg yesterday.
Schalke sit seventh in the Bundesliga table.
