In 1960, at the start of a tumultuous decade that saw major global change, the Intercontinental Cup was born. For the first time, this ambitious annual cup crowned a world club champion, pitting the kings of the two great footballing continents - Europe and South America - against each other. In an era before money ruined the global balance of football, neither dominated. From the Estadio Centenario and the Maracanã, to Old Trafford and the San Siro, the most iconic stadia in world football hosted Intercontinental Cup games. The star players of their respective generations participated - from Puskás and Di Stéfano in the inaugural 1960 edition, to legends such as Pelé, Ronaldo, Zico and van Basten. When Two Worlds Collide charts the Intercontinental Cup's colourful 44-year history, from its trailblazing inception to 2004 when the last ball was kicked in Yokohama. The controversial clashes of the late 1960s, the cup's decline in the 70s and the pivotal 1980 rebirth in Japan are all covered.
