As the cup holders Feijenoord participated in the European Cup 1970-71 despite relinquishing the Dutch title, which was won by Ajax. Feijenoord were eliminated in the first round following a surprise defeat by Romanian team UT Arad. However, as reigning European champions Feijenoord faced Estudiantes La Plata in the Intercontinental Cup. The first match in Buenos Aires' La Bombonera finished in a 2–2 draw. Back in Rotterdam Feijenoord managed a 1–0 victory (winning goal by Joop van Daele) to win the world club crown, the first Dutch team to do so. Estudiantes player Oscar Malbernat got frustrated and grabbed Van Daele's glasses and trampled on it. "You are not allowed to play with glasses." was his excuse, "At least not in South America." In 1971 Feijenoord won their 10th Dutch Championship.
