I coach girls U12 rec. Last season, was our first year of full-field 11-asite soccer and we needed a formation for the first time. This book did a great job of explaining the pros/cons of the 4-4-2, along with some info on how to determine if it was right for my team, based on the players and their abailities. Further, it listed a few drills for introducing the formation along with some plays and considerations for game situations.
This book is by no means an introductary soccer book, but it laid out the information in a clear consise staright forward manner. I purchased 2 more for my assistant coaches as well.
