Marcelo Bielsa is one of football's greatest eccentrics and greatest enigmas. This will be the first English biography of one of football's most contradictory characters.
He has coached some of the greatest names in world football - Gabriel Batistuta, Carlos Tevez, Javier Mascherano, Juan Sebastian Veron and Ander Herrera. He has been cited as a mentor by Pep Guardiola, Mauricio Pochettino and Diego Simeone.
Yet Marcelo Bielsa remains one of the great enigmas of world football - a fabulously innovative and obsessive coach, who has transformed Leeds United, Marseille and Athletic Bilbao. He also lasted two days at Lazio and led Argentina to their greatest footballing disaster.
Featuring interviews from across South America, Europe and Yorkshire, The Quality of Madness is a comprehensive and compelling biography, tracing Bielsa's story from growing up as a member of one of Argentina's most remarkable families to his revival of Leeds.
Bielsa has long been known as 'El Loco' - the Madman - and yet as Tim Rich's revelatory study reveals, there is mercurial method and audacious logic to the madness.
