If you are a coach, this book is for you. Its concepts are complex and the book assumes an already detailed knowledge of the game. There are several attacking patterns that I guarantee will help your team, as well as concepts and drills to improve individual and group attacking play. For someone who played defense in college and specializes in defense at the collegiate coaching level, the book is helpful if one-sided. The Italians focus on a zonal defense, and in general flat-back defense is detailed. There is some very good stuff in here to help build a defense. Additionally, almost any formation you can imagine is given a quick glance by a professional coach who uses it and notes its advantages and disadvantages. The one criticism I have is the clumsy writing--these guys are definitely not American.
