This full-color book with interactive videos provides a detailed tactical analysis of the defensive secrets of the world's best coaches. The "phase spaces", broken down in detail on these pages, are the key to the defensive success for Hans-Dieter Flick, Pep Guardiola, Jürgen Klopp and Marco Rose. However, they are also essential when attacking since both actions are indivisible and interrelated in football. How do you arrange the height of your block and your positional scheme? What kind of pressure do the players exert? What is the team's attitude towards the opponent's first pass? How do they react to the opponent's progression through the center zone or on the wings? Dive into the answers provided by these top coaches. In addition, this book offers training activities so that the readers can use and adapt them for their own teams. These are exercises based on the situations analyzed in this book, with the objective of creating patterns of play so that the players can read and anticipate the movements of their opponents.
