Pep Guardiola has already chosen his next club after telling Bayern Munich of his decision to leave at their Christmas party, according to chief executive Karl-Heinz Rummenigge.
Bayern confirmed Guardiola's departure at the end of this season on Sunday.
The former Barcelona manager, 44, has been linked with Manchester City, Manchester United, Chelsea and Arsenal.
"I think I know where he is going - but I want to leave the announcement to him or his new employer," said Rummenigge.
The former Bayern and Germany striker says he holds no ill feeling towards the Spaniard despite his decision to leave the Bavarian club next summer.
"He came over to me two weeks ago at our Christmas party and told me that he was looking for a new challenge," Rummenigge told German newspaper Bild.
"He was almost apologetic. I'm not disappointed in him."
Former Milan, Chelsea and Real Madrid boss Carlo Ancelotti, 56, has signed a three-year deal to replace Guardiola at Bayern.
Rummenigge says he was wary Guardiola would decide to move on after noticing signs the former Spain midfielder appeared to be getting restless in the summer.
"You could read between the lines and that was something that we should have interpreted," he added.
"We did take note of it, but we just wanted to give him time to make up his mind in peace."
