Werder Bremen parted ways with their coach Florian Kohfeldt one day before the end of the season.
This was announced by the heavily relegated Bundesliga club this Sunday.
Club legend Thomas Schaaf should now save the green-whites from the first relegation since 1980.
"Unfortunately after the game in Augsburg we were no longer convinced that we would be able to stay up with Florian Kohfeldt," said sports director Frank Baumann.
On Saturday, the green-whites suffered a 2-0 defeat at FC Augsburg in the basement duel and slipped to 16th place.
The lead over 1. FC Köln on the first direct relegation place is only one point.
Werder Gladbach will host on the last match day, Cologne will play against FC Schalke 04.
The 60-year-old Schaaf, who had already trained Werder for 14 years in the past and, among other things, won the double with the green-whites in 2004, will travel to the quarantine training camp in Barsinghausen on Sunday.
In addition to the previous coaching team, Wolfgang Rolff, who will act as co-trainer, is at his side.
Schaaf's commitment is limited until the end of the season.
Kohfeldt had already faced the end three weeks ago.
At that time, those responsible around managing director Frank Baumann only expressed confidence in the 38-year-old for the DFB Cup semi-final against RB Leipzig after the 1: 3 at Union Berlin.
Werder lost 2-1 in extra time, but the bosses saw the team's passionate performance as a sign that Kohfeldt could succeed in saving.
Baumann and Co. also commented positively on the 0-0 win against Bayer Leverkusen last weekend.
But after the 2-0 defeat in Augsburg, the eighth defeat in the past nine games, the belief in Kohfeldt was gone.
