Under-fire Carlo Ancelotti could be sacked as Bayern Munich boss as early as Thursday, according to a report in Germany.
Sport Bild claim the Bayern board are to hold a crisis meeting after returning from Wednesday's 3-0 Champions League loss to Paris Saint-Germain.
It was Bayern's second defeat of the season, following a 2-0 loss at Hoffenheim, and came in a week in which they surrendered a 2-0 lead over Wolfsburg to draw 2-2 at the Allianz Arena.
Speaking afterwards, Robben refused to say if the team still backed their coach, claiming any comments he made would be "one word too many".
"I will not answer that," he said. "It was a painful defeat, we can talk about this. When it is a game as big as this, you never want to lose."
Rummenigge hinted at possible repercussions for the result, saying: "It's a loss we have to talk about, we have to analyse.
"I think what we saw was not Bayern Munich. I think we all agree on that. Then there is nothing to misunderstand or to interpret wrong."
