Based on the book by Jack Detchon - Technical director, Tony Waiters The success of Brazil with a zonal system in the 1994 World Cup - where they were the best defenders as well as the best attackers - has focused attention on this method of defending. No single system of play - zone or man marking - is best for everyone. But the best coaches and players will know about both and will be able to play in them and against them. If players understand how to play effectively in a man-marking/ sweeper system AND understand how to play in a zonal system, they will be better players. All teaching points are illustrated with footage from world class players and teams.
