HAMBURG, Germany -- Hamburger SV have promoted under-23 coach Josef Zinnbauer to first-team manager after sacking Mirko Slomka.
Zinnbauer has been given the position "until further notice," assisted by former youth coach Patrick Rahmen.
Slomka was fired late on Monday after the club's poor start to the season. Hamburg are scoreless in three Bundesliga games and bottom of the table with a single point.
Beiersdorf told his club's official website: "Joe has been coaching and getting results with our under-23 side (eight wins from eight games) in the Regionalliga Nord, which is proof that he can lead a team and help them gel together quickly as a team.
"He is a very open, outward-looking guy who can lead the club both emotionally and -- on the other side -- structurally with some excellent work.
"We are confident that he can ignite a new spark within the squad and will be a strong leader as he prepares for the tasks ahead. In doing so, we will support them as a club by all means."
The 47-year-old Slomka just saved Hamburg from relegation last season following the dismissals of predecessors Bert van Marwijk and Thorsten Fink. His last game was a 3-0 loss at his former club Hannover.
Hamburg are the only side to have played each season in the Bundesliga since the league was formed in 1963.
Zinnbauer's first game in charge will be at home to Bayern Munich.
