For twenty years, Andy Nicholls was one of the most active football hooligans in the country and a leading figure among the violent followers of Everton Football Club. Classified as a Category C thug - the worst kind - he amassed more than twenty arrests for football related offences and is banned from every ground in the UK. Scally deals head-on with the vicious knife attacks perpetrated by the shadowy County Road Cutters, chronicles the bitter Manchester-Merseyside battles that left scores injured and describes enduring rivalries with the gangs of Aberdeen, Chelsea, Millwall, Middlesbrough and many more. Scally caused a storm of controversy on first publication and is widely acknowledged as the most revealing, most shocking book ever written about soccer gang culture.
