Retired footballer Gerald Asamoah has been spared by Schalke following their mass sacking of technical staff after a revolt from players.
The German Bundesliga side are at the bottom of the league and have struggled all season. Due to this, players revolted and major sacks were made.
Coach Gross, sporting director Jochen Schneider and team coordinator Sascha Riether were all relieved of their duties in Sunday's mass clear out.
"The decision had become unavoidable after results against Dortmund and Stuttgart," said Schalke chairman Jens Buchta in a statement following Schalke's 5-1 loss to Stuttgart on Saturday, a week after defeat to local rivals Borussia Dortmund.
"The team now owe it to the club and the fans to be as successful as possible in the last third of the season."
Gerald Asamoah, who currently has a UEFA A license and works closely with the first team, has been spared for now.
Asamoah played for the German national team during his days as a footballer.
