Way too much of this is either plain common sense else known to anyone who has played/watched/coached football for a year. it's intensely logically laid out and tells you how to handle the four attackers coming your way, with one section per attacker who has the ball, and sub-sections depending on who the attacker passes to.
Snag is, defending your left flank is (presented as) simply a mirror of defending the right flank, and defending left midfield is a mirror of - you guessed it - defending right midfield. So almost half the book is the other half word for word but with the diagrams and words "reversed". And to me the defending is plain common sense, seriously - no gems of trickery or guile at all.
Funny enough I found the shorter sections on attack play quite valuable - how the front two should execute running patterns to lose their markers.
So, I would recommend this for a novice coach only.
