“After Brazil had won the World Cup in 1958 using a back four, the rest of the world were forced to react. Almost overnight the old-school W-M formation, which dominated tactical thinking almost everywhere else, seemed outmoded and needed revision. As a result, teams essentially took one of two routes – and the route they chose was determined almost entirely on national grounds, with that choice continuing to have an effect on the basic tactical template in those countries today.” World Soccer – Jonathan Wilson
