Their first match took place on 14 September 1968; Chelsea won 4–0. Since then, the sides have met a further 45 times, making it the most common West London derby since the 1960s. The clubs developed a rivalry in the 1960s and 1970s when both were playing top-flight football and competing to be among London's top sides, with Chelsea winning the FA Cup, Cup Winners' Cup and League Cup, and Rangers winning the League Cup and finishing as league runners-up by a single point.
