The Netherlands international feels the veteran coach is the right man for the job, and hopes he will not leave the club when his contract expires at the end of the season
Heynckes recently hinted that the 2012-13 campaign could be his last year with the Bavarians, but has since denied that he has already made a decision about his future.
"There's no one better suited to coach Bayern than Heynckes at the moment," Robben was quoted as saying by Bild.
"He is doing a great job. The chemistry between the coach and the players is perfect. I hope that he will continue at Bayern if he still feels fit enough."
Heynckes joined Bayern from Bayer Leverkusen in the summer of 2011, and guided them to the Champions League final last term.
