The 67-year-old will come to the end of his contract with Bayern at the end of the season and will be replaced by Pep Guardiola.
"When I think of [former Chancellor of Germany] Konrad Adenauer assuming office at 71, and now our new Pope who is 76, then I think can still do something at 68," he told Liga Total.
"I would not consider that directorial role. I am only going to reveal my future after the end of this season."
Bayern are currently 20 points clear at the top of the Bundesliga.
