28-year-old Julian Nagelsmann is the youngest coach in Bundesliga history

Nagelsmann has been handed a three year deal as head coach for Hoffenheim and as a result of it starting sooner than originally planned, he is now the youngest head coach in Bundesliga history. 

Nagelsmann moved into coaching after suffering from persistent knee problems and no longer being able to play professionally.
