The 1964–65 season of the European Cup Winners' Cup club football tournament was won by West Ham United in a final at Wembley Stadium against 1860 Munich. West Ham's Bobby Moore captained a side that also included Geoff Hurst and Martin Peters just one season before all three went on to star in England's World-Cup-winning side of 1966. As a result of their CWC success, Bobby Moore became the only captain to climb the Wembley steps to be presented with three different trophies in three successive seasons (English FA Cup and European Cup Winners' Cup with West Ham in 1964 and 1965 respectively, then the World Cup with England in 1966).
