This book examines the offensive and defensive phases of the popular 3-4-1-2 and 4-2-3-1 systems of play. Starting with a discussion of the characteristics of the players at each position, it builds into a comprehensive tactical overview complete with build-up options and attacking schemes in the attack phase and marking responsibilities and zonal movements in defense. Finally, the author suggests strategies for countering specific formations out of both the 3-4-1-2 and the 4-2-3-1.
