RB Leipzig, New York's sister club, announced Monday that Marsch would be joining the club as an assistant coach while sporting director Ralph Rangnick assumes the managerial reins in a caretaker role.
Julian Nagelsmann will eventually take over as head coach for the 2019-2020 season after he fulfills his current contract with Bundesliga rivals TSG Hoffenheim. Marsch's contract is for two seasons, meaning he will remain a part of the staff when Nagelsmann assumes the position.
RB Leipzig were founded in 2009 and have worked their way through the German football pyramid, earning promotion to the Bundesliga before the 2016-2017 season. They finished sixth last season after an impressive second-place performance in their maiden campaign.
Marsch departs after three-and-a-half seasons in New York, during which he became the winningest coach in club history with a record of 58-35-25. He led the club to the 2015 Supporters’ Shield, a U.S. Open Cup final appearance, and two trips to the Concacaf Champions League, including a semifinal appearance in 2018.
