Football books usually promise dressing room gossip. This one is filed under sport and technology at once, and that double shelving is the clearest description of what Ian Graham is doing: treating the game as a problem that yields to measurement.
The argument, put simply, is that intuition has been the most expensive habit in football, and that clubs willing to test their instincts against evidence have quietly changed the way squads get built. It is written for people who love the game rather than for statisticians, which is the harder brief of the two, and the numbers arrive as narrative rather than as tables.
