The 1970–71 season of the European Cup Winners' Cup football club tournament was won by Chelsea in a replay against Real Madrid. Defending champions Manchester City were eliminated by Chelsea in the semi-finals, only the second ever tie in the competition between two clubs from the same country. These two sides would later compete in the 2021 UEFA Champions League semi-finals, with Chelsea winning 3-1. The finals were played in Karaiskakis Stadium in Piraeus, Greece.[1][2][3]
