The football aside, one of the most fascinating aspects of Schalke's fixture at home to Hoffenheim on Matchday 23 was the touchline battle of wits between the two youngest head coaches in Bundesliga history: Domenico Tedesco, 32, and Julian Nagelsmann, 30.
The duo are close friends, having taken their coaching licenses together and worked as colleagues at Hoffenheim, with Tedesco taking over the reins of the U-19s when Nagelsmann was appointed head coach in 2016.
