Brighton & Hove Albion have appointed 31-year-old Fabian Hurzeler as coach on a contract until 2027, the club said on Saturday, making him the youngest manager in Premier League history.
Hurzeler replaced Roberto De Zerbi who left at the end of the league season having helped them qualify for European competition for the first time during his spell in charge.
The American-born coach guided St Pauli to the top of the second-tier in Germany, earning promotion to the Bundesliga as champions.
"From the start of the process to appoint our new head coach, Fabian was always a standout candidate and one who had caught our attention with his exceptional work at St Pauli over the past eighteen months," Brighton chairman Tony Bloom said.
"He has a style of play that aligns with how we want a Brighton & Hove Albion team to play, and I'm confident it is one our supporters will appreciate and enjoy.
"Fabian also has an excellent coaching pedigree and has worked with the German federation at various age group levels. We are really excited to start working with Fabian to prepare for the upcoming season."
Brighton finished 11th in the league last season after a gruelling campaign where they also reached the last 16 of the Europa League.
"The club has made incredible progress over the last few seasons and the aim is to continue building on that success," Hurzeler said.
"I am relishing the opportunity to coach in the Premier League, and I can't wait to meet the players, staff and, of course, the fans."
