#1 Julian Nagelsmann (Hoffenheim) - 31 years old
Widely considered to be the best young manager in the business and the next in line to be RP Leipzig manager, Nagelsmann has led a relatively young Hoffenheim side to a Champions League spot in 2017-18.
He has continued his good work in this season as well. Nagelsmann idolizes Pep Guardiola and it is evident in Hoffenheim's play as well with the German club playing usually in a 3-5-2 formation with Reiss Nelson and Joelinton up front with Belfodil also providing an option. Kerim Demirbay is pivotal to Nagelsmann's style of play which involves slick-passing game similar to that of Wenger's Arsenal.
The German has installed a video wall for better analysis for the players. 2019-20 would see Nagelsmann coaching RP Leipzig, which is a hub of young exciting talent. It is a match made in heaven and would surely be successful in the coming years.
