Julian Nagelsmann: Tactician. Team manager. Beacon of hope. Julian Nagelsmann made football history even before turning 40. As the youngest head coach in the Bundesliga, as an innovator at TSG Hoffenheim and RB Leipzig – and now as the national team coach, who had to take over and rebuild a deeply unsettled national team before the 2024 European Championship on home soil. And thanks to his success, he has given German fans renewed hope for the 2026 World Cup. Initially considered a tactical nerd, he has since earned a reputation as a modern strategist and emotional leader. With tactical intelligence and unconventional methods, Nagelsmann made a name for himself early on as a detail-oriented pragmatist. This book illuminates what makes the coach tick: his ideas, his approaches, his successes, but also his brief time at FC Bayern Munich is examined. Justin Kraft analyzes his journey from a failed professional playing career to national team coach, through his stints at Hoffenheim, Leipzig, and Munich.
