In an ever-changing world, such as soccer's, only intelligence may truly help, since, besides being able to act effectively, it is essential to know how to think about the best way to act. Therefore, in the more recent years of modern soccer, the tactical component has been increasingly valued and diffused. Particularly in Brazil, this dimension of sport performance has been studied and applied by many professionals of this field, from the youth academies to professional level. This book was conceived to help those who devote much of their time to improving the quality of the game, and to training highly enlightened, creative and intelligent players. Hence, this work presents procedures and ideas that, besides assisting in the task of evaluating the tactical performance of soccer players and teams, also allow improving their expression throughout the learning and training phase.
