Klaß, who made 34 appearances in the fourth tier with Oberhausen over two seasons, previously played Jahn Hiesfeld in the fifth-tier Oberliga as well as for the youth teams of Duisburg.
He has signed a one-year contract with Braunschweig and is the club’s fourth signing of the summer. Fellow centre defenders Jannis Nikolaou and Michael Schultz, plus defensive midfielder Dominik Wydra, have already been signed for new coach Daniel Meyer.
Their sporting director Peter Vollmann said that the club, who have been keeping a close eye on Klaß’s development, are “sure that he can make the leap from the Regionalliga to the 2. Bundesliga.”
He added that the 23-year-old is “a duel-strong player with tremendous calm on the ball,” who fills their requirement for a left-footed centre-back.
Klaß meanwhile says he is “very happy to be able to play for such a traditional club that is highly regarded by fans and the city.” He is naturally hoping to “use my skills to help the team and the club.”
The club also announced on Wednesday that Marc Lorius has become their new athletic coach, whilst their seven-year partnership with main sponsors SEAT has come to an end. There has also been confirmation that Kevin Goden and Alfons Amade will leave following the end of their loan spells at the Eintracht-Stadion.
