For more than 120 years, Rangers and Celtic have vied for supremacy in one of the world's sporting hotbeds. The rivalry between the two teams is among the fiercest anywhere in sport, making an Old Firm derby much more than a football game. Controversy is rarely far away when the Glasgow giants meet, but amid the fallout that invariably follows their contests, the actual game is often forgotten. In Follow, Follow, Iain Duff recounts the greatest footballing moments of Rangers' illustrious history in Old Firm clashes, from their very first competitive win over Celtic, in the 1893 Glasgow Cup final, through to the 1-0 victory at Ibrox that was a vital factor in Rangers' 2009-10 SPL title win. The intervening years saw famous Old Firm contributions from legendary Ibrox names such as Gillick, Meiklejohn, McPhail, Baxter, Johnston, McCoist, Cooper, Laudrup, Ferguson and Novo, all of which are revisited here, along with the goals, the flare-ups and the controversies that make these derby days simply unforgettable for every Rangers fan.
