Peter Hyballa is no longer the coach of the Danish second division football club Esbjerg FB.
"I have resigned," said the 45-year-old on Wednesday the German press agency.
The reason is slander and hunted down by the tabloid media and the influential players' union.
His family was also affected, said Hyballa.
“I can't accept that.” The coach, who had only taken over from the relegated team for the new season and had trained Alemannia Aachen in Germany, said that he was foregoing a severance payment.
The background is a dispute with parts of the team.
A good month ago, 21 players had accused Hyballa in an open letter of not having the professional and human qualities to lead the team.
His tough training methods would have resulted in injuries.
In addition, they have experienced daily threats of layoffs, ridicule, sexist and humiliating remarks as well as regular bullying, which goes far beyond the already wide boundaries of the football world.
Hyballa, who appeared as a ZDF tactics expert during the European Championship, rejects the allegations.
"This is character assassination, I defend myself against it," he said.
There were "two or three ringleaders" who raised the mood against him and put other players under pressure.
The US investors who bought the club earlier this year are on his side. He also has a friendly relationship with the former Bundesliga professional Rafael van der Vaart, who was introduced on Tuesday at his instigation as the new co-coach.
