The 26-year-old has signed a three year deal with Hertha Berlin and will join the club on a free transfer as his contract with Bayern has expired.
“Hertha BSC and Berlin are a new challenge to which I very much look forward after 15 years in Munich,” Ottl said.
“Andreas Ottl is an experienced Bundesliga player whose quality will help us not only in the next season, but in the coming years,” Hertha sporting director Michael Preetz added.
