Sports journalist Luca Caioli has written a frank biography of Argentine football player Lionel Messi. In an effort to understand how an ordinary boy, also burdened with a physical disability, becomes a world legend, the author collects information wherever possible. He listens to confidential stories from Messi's family and friends, his coaches, doctor, former players, sports journalists and television commentators and learns many interesting details from the life of a boy who stopped at nothing to achieve his dream and ultimately became one of the greatest football players in the world.
