In many parts of the world, football ("soccer" in the U.S.) represents a way of life. Roughly 150 million players register for professional or amateur leagues and roughly two billion people of all ages across the globe enjoy football recreationally. Few people, however, know the origins of the game or understand how its tactics evolved. This informative work traces the historical development of football and its team tactics from 1863--the year the English Football Association was founded--to the present. It describes significant formations and trends, identifies the major reasons for tactical changes, and introduces the most influential leaders in the sport. Also included are a glossary of relevant terms, a history of the World Cup, and a biographical list of famous players of the past. This essential resource for coaches, players, and fans will foster a greater understanding of and appreciation for the world's most popular team sport.
