Fine Margins is the definitive story of how two mainstays of English football took their feuding on to the game's biggest stages. The Manchester City and Liverpool rivalry is synonymous with the Premier League, but its roots go back much further. For over half a century, these two clubs from opposite ends of the M62 have been perennial thorns in each other's side. Bill Shankly laid the groundwork in the late 1960s before a series of clashes a decade later further stoked the fires, culminating in an attack on City's team bus in 1981 after they beat Liverpool 3-1 at Anfield. The feud was reignited in the mid-1990s when Liverpool relegated City on the final day of the 1995/96 Premier League season. When they returned to the top flight, Manchester's blue half became the scourge of Merseyside's Redmen, snatching players and points away from them. Countless managers, players and directors have continued what started in the Bill Shankly era, with the rivalry ramped up a notch through the reigns of Pep Guardiola and Jurgen Klopp.
