Book excerpt: 'Access inside the changing room and behind the scenes that any journalist or writer would kill for - Perarnau's insights are astonishing' - Graham Hunter 'Write about everything you see. Be as critical as you like' - Pep Guardiola to Marti Perarnau, summer 2013 Marti Perarnau was given total access to Bayern Munich during season 2013-14. This book represents the first time in the modern era that a writer has got this close to one of the elite teams of world football. At the invitation of Pep Guardiola, he shadowed the Catalan, his staff and his superstar players during training and on matchdays. Bayern smashed domestic records on their way to the double, but were humiliated by Real Madrid in the Champions League semi-final. Perarnau was with them every step of the way. Perarnau is with Guardiola as he is courted by the world's greatest clubs during his sabbatical in New York. We hear Guardiola explain in detail the radical tactical moves which transform Bayern's season and reprogramme the players who will win the World Cup with Germany.Perarnau talks exclusively and in fascinating detail with players such as Arjen Robben, Manuel Neuer, Philipp Lahm, Thiago Alcantara and Bastian Schweinsteiger. Pep Confidential is much more than the story of a season - it is also a lasting portrait of one of the greatest coaches in sport.
