Bayern Munich CEO Karl-Heinz Rummenigge is refusing to offer any guarantees over the future of Franck Ribery.
The 35-year-old winger's contract expires at the end of the season and it is unclear whether he will be offered an extension.
Ribery has enjoyed huge success since joining the club from Marseille in 2007, most notably inspiring them to a treble of Bundesliga, DFB-Pokal and Champions League wins in 2012-13, but injury problems have restricted his impact in recent seasons.
Rummenigge plans to hold talks with the player but admits he is unsure what the outcome will be.
"We've had some amazing years thanks to him. I have huge respect for Franck," he told Eurosport.
"You have to be open and honest. At some point, we'll have a conversation with him and his agent and then make a joint decision. I can't predict what that will be."
Ribery came off the bench in Friday's 3-2 win at Augsburg for his 16th Bundesliga appearance of the campaign.
Veteran team-mate Arjen Robben, also 35, has already confirmed this season will be his last at Bayern.
