Hamburg have completed the signing of goalkeeper Jaroslav Drobny from Hertha Berlin on a free transfer.
Drobny has penned a three-year deal with Hamburg after Hertha were relegated last season.
He told the club's official website: "I am looking forward to the challenge. I am convinced that we will have a great and successful season.
"You only have to look at the squad to see the potential here. I imagine they weren't satisfied with their performance in the Bundesliga last season.''
