Christian Heidel – The Maker: Son of former Mainz mayor Herbert Heidel, Christian Heidel served from 1992 to 2016 as the club’s manager and by the end of that period was the longest-serving manager in the Bundesliga. For more than two decades he was the fixed point in Mainz’s daily business and became an honorary member and part of the club’s old guard. Even his later move to Schalke in 2016, where things went only moderately well, did little to alter his standing in Mainz.
