"The team that wins the most one-on-ones wins the game." This "old soccer adage" is proven true again and again in all age and playing classes. For this reason systematic and deliberate training in proper one-on-one behaviour is an indispensable element of modern soccer training. This book is designed to do justice to the great significance of the one-on-one situation in soccer. With competence and in great detail the authors describe everything you need to know about one-on-one behaviour. In the introductory section the general significance and the physical, technical, and tactical as well as the mental and emotional aspects of the one-on-one "duel" for the ball are covered. The following chapters deal with the particular peculiarities of one-on-one behaviour in the various team sections - from the goalkeeper through the backs (marking, challenging and chasing opponents, covering a man/area) to the forwards and mid-field players (dribbling, feigning, playing around and over, running free).
