Argentine side Boca Juniors qualified for the 1977 and 1978 editions, for which the European champions, English club Liverpool, declined to participate on both occasions. In 1977, Boca Juniors defeated European Cup runners-up, German club Borussia Mönchengladbach, 5–2 on aggregate. Boca Juniors declined to face Belgian club Brugge in 1978 leaving that edition undisputed. Paraguay's Olimpia won the 1979 edition against European Cup runners-up, Swedish side Malmö FF, after winning both legs. However, the competition had greatly declined in prestige. After the 0–1 win of the South Americans in the first leg at Malmö, which saw fewer than 5,000 Swedish fans turn up, Spanish newspaper "El Mundo Deportivo" called the Cup "a dog without an owner".
