Mainz 05 as a “coaching university”: Jurgen Klopp, who won six trophies with Liverpool including the Champions League in 2019 and the Premier League in 2020; Thomas Tuchel, Champions League winner with Chelsea in 2021; and Bo Svensson, an internationally coveted coach — all three began in Mainz. No other Bundesliga club has produced three coaches of international stature in such a short space of time.
