The dark, malignant loathing shared by the followers of Liverpool and Manchester United has seeped into every aspect of life in the two cities. Football is not a barometer of disdain, as it is in places like Glasgow or Istanbul or Moscow. In northwest England, it is the engine of animosity. How did it come to this? Why did things turn so nasty? And what does it say about the two cities in which the clubs are based? Written by a Scouser and a Manc in a rare collaboration, this book addresses the divide by talking to those involved in ten seminal football matches. It speaks to the characters who patrolled and provoked the rivalry: Alex Ferguson, Kenny Dalglish, Steven Gerrard and Gary Neville, among many others.
