Bierhoff, who decided the European Championship final in 1996, has worked for the German Confederation since 2004.
“I have told the chairman of my decision today. I am paving the way for others to choose a new direction,” he said in a statement.
Germany also made a fiasco at the World Cup 2018 in Russia when they finished last in the group, behind, among others, Sweden.
“I do not leave without necessary self-criticism. We have not been able to repeat our previous successes in the last four years. Some decisions we believed in a lot have been proven wrong. No one regrets it more than I do. I take responsibility for that,” says Bierhoff.
Attacking star Oliver Bierhoff scored 37 goals in 70 internationals for Germany during his playing career.
