Leo Messi, Cristiano Ronaldo, Kylian Mbappe — even if you are not a sports fan, you definitely know these names. They have millions of followers on social networks, they are one of the main heroes of popular culture, they are football stars. Somewhere in the shadow of these luminaries, the coach's profession was undeservedly lost.Dietrich Schulze-Marmeling, with the pedantry inherent in the Germans, describes the history of the formation of the coaching profession from the moment football was born, turning it from a game of gentlemen into a game of hard workers, and then into a professional sport. This is a detailed story about coaching ideas, innovative tactical decisions and personalities that influenced the development of the game. You will have to find out: how the British style of 'hit—and-run' was born; what the 'Danube school' is; how the 'W-M' system was created; why the Dutch 'total football' changed the philosophy of the game; how Valery Lobanovsky was the first to practice a scientific approach to the game; why Guardiola became the coach of Barcelona, and not Mourinho, and what does Johan Cruyff have to do with it; how Jurgen Klopp breathed a new passion into the game; and many more fascinating pages of football history.You have in your hands the history of the people at the edge — those who made football the way we know it today.
