Bayern Munich plan on hiring a new manager by the end of April.
CEO Karl-Heinz Rummenigge has also finally ended speculation that Jupp Heynckes could return next season
"It's Heynckes wish to retire at the end of the season," Rummenigge said.
Bayern will not pursue any manager who does not speak German.
"We want a German-speaking coach," Rummenigge added. "That's the way it will be."
Rummenigge confirmed Thomas Tuchel was a candidate but he's committed to another club.
"Our sporting director Hasan Salihamidzic has held talks with coaches and Tuchel was among them," the CEO said, noting that he couldn't say a "bad word" about Tuchel.
"He informed us that he's signed for another club. But that isn't a problem for us, we are relaxed."
