This is the first time I read a book about football that is not in the language of wood. In this book you feel the experience of a man of experience and land that has rubbed the greatest (not necessarily of great men). This changes the players who were not even 30 years old and who write biographies as if they had a career with Maradona. Loved behind the scenes, hidden from the public, the small world of football. I sometimes had the impression of being with Bruno Derrien when he comes home alone after incurring the wrath of an entire stage. Having followed a little this little world, Derrien you never, even in business. When we see the errors of some current referees, one can easily imagine that his eviction is due to personal reasons for his skills. To advise those who want to know the insidious and perverse influence of certain presidents of clubs in the highest spheres are silent for fear of the alienating, or surprising relationships of players and referees, and fans ( Lyon's too) who do not want to open their blinders, and anyone planning to embrace the refereeing career. A light and serious book at a time which reads easily and household suspense. It's very funny at times, especially when he speaks of anecdotes that ring true. Some replicas have nothing to envy to a good film Audiard. When is the film?
