The Bayern Munich board will reportedly meet on May 22 to decide the futures of CEO Oliver Kahn, sporting director Hasan Salihamidzic and new coach Thomas Tuchel.
The German giants have been in freefall since firing Julian Nagelsmann as manager in March, and replacing him with the former Chelsea boss.
Bayern Munich have been eliminated from the Champions League by Manchester City and the German Cup by Freiburg.
They have also lost top place in the Bundesliga, following a 3-1 defeat to Mainz on Saturday coupled with Borussia Dortmund's 4-0 home win over Eintracht Frankfurt.
