Journalist Andy Mitten investigates the deep-seated rivalries that transcend the sport itself, utilizing a collection of firsthand accounts from supporters to map the social and political landscapes surrounding these fixtures. By focusing on the fan experience, the author constructs a framework that explains how local identity, historical grievances, and community pride manifest within the ninety minutes of a match.

The text provides a comprehensive, ground-level view of football culture that prioritizes the lived experience of the fan over mere match statistics. Its reliance on anecdotal evidence and personal testimony offers a vivid, albeit subjective, exploration of the tribalism inherent in global sports.
