The German FA (DFB) is set to appoint national hockey team coach Markus Weise to work for its forthcoming academy.
Weise, 52, has won back-to-back gold medals at the last two Olympic games with the German men's team, adding to his 2004 triumph with the women's hockey team.
"An era will come to an end at the hockey association in mid-November when the men's national team coach Markus Weise will leave one of the most successful Olympic associations to move into football," a statement on the website of the German hockey association (DHB) read.
DHB president Wolfgang Hillman added: "He's a coaching personality which can't be replaced by anyone in hockey."
Hillman told SID he was frustrated by the lack of communication between the associations.
"I have to say clearly that in such a personnel matter there has to be a signal from their presidency to ours," Hillman said. "I can't look at it as a partnership when this has not happened."
He added that the switch at this stage is "difficult" since the association has been preparing for the 2016 Olympic Games since May.
In his explanation for why he had made the switch, Weise acknowledged that the circumstances were not ideal but cited his age, adding: "In the end, those opportunities never come at the right time."
Speaking at a news conference in Munich on Tuesday, Germany general manager Oliver Bierhoff said that appointing Weise was "a very important personnel matter for our academy project" but added that the paperwork was not done yet.
The DFB academy in Frankfurt was last year described as "the future of the association" by former president Wolfgang Niersbach, who resigned amid the 2006 World Cup scandal earlier this week.
The start of the construction work for the academy is planned for early 2017, and the DFB has targeted a completion date of late 2018.
Weise is the second hockey national team coach to make the switch into football.
In 2006, then Germany coach Jurgen Klinsmann coach had tried to sign Bernhard Peters, who was then in charge of the men's hockey team.
Peters, now 55, ultimately left the DHB later that year and joined Hoffenheim, then in the third tier, as a director. In 2014, Peters joined Hamburg as a director of sport.
