Borussia Mönchengladbach have confirmed that head coach Markus Keller has resigned with immediate effect, citing personal reasons. The announcement came just hours after the club’s 1–1 draw with Bayer Leverkusen. Keller’s unexpected departure leaves the team scrambling to find a replacement as they sit mid-table in the Bundesliga. Assistant coach Sven Baumgartner will take charge temporarily while the board considers permanent options. Keller, who joined Gladbach two years ago, is credited with stabilising the club after a difficult period. Players and fans have reacted with shock but have sent messages of support to Keller and his family.
