ABSTRACT
Studies show that changes in managerial position do not have any impact in the long run. Nevertheless, many club boards of teams in a precarious situation tend to go for a new manager. Positional data open up many new possibilities to model the tactical aspects of the game, find patterns, and create novel, advanced performance measures. This chapter investigates whether these can detect changes in the tactical performance of a team with two successive managers. The example under investigation comes from the German Bundesliga and reveals that after the installation of a new coach, a slight change in formation and in playing style led to measurably different performance benchmarks, highlighting the desired effect.
