This is the first volume of the three-part series Revolution in Soccer , which aims to change soccer drastically and align practice with the latest scientific standards. There is an abundance of books and websites with games and exercises. Picking out one and implementing it is not that hard. However, all those books and websites fail to explain in detail how to develop a game or an exercise and when which type of training makes sense. Nor how to structure a single practice session – let alone an entire season. This book is going to change that. After reading this book, you will not only have the ability to train your players according to a clear philosophy, but you will also be able to design your own games and exercises for all eventualities. This book provides innovative food for thought so that soccer can finally experience the revolution that is long overdue: You are going to learn why the number 8.1 is a crucial one for developing young players, why your training should be complex but not complicated and why the so-called constraints-led approach in games is the most effective methodology. This book therefore does not contain a multitude of different games and exercises that are randomly strung together, but ten complete exemplary practice sessions that have been planned out down to the last detail for you. “If practice is easy, the game is difficult. If practice is difficult, the game is easy.” Simon Schröttle has his own soccer academy, is a player coach and has many years of experience as a player and coach at German Bundesliga side FC Augsburg. He is one of the leading experts on the constraints-led approach in soccer. This book is for all coaches and club representatives who are willing to break new ground. It is intended for all coaches, regardless of level–whether it is a father who is only coaching the team because no one else wanted to do so, or a coach at an academy who has the goal of accompanying his players on the way to their dream of becoming a professional player. It is for all clubs that want to establish a consistent philosophy, which I strongly recommend. We must all work together to ensure that we once again develop better players at the top level and that players do not drop out on grassroots level.
