Despite the statistics, this period was characterised by the existence of the "Big 4" ("Velika četvorka"), a colloquial name attributed to the four larger clubs in the country, Red Star, Partizan, Hajduk Split and Dinamo Zagreb which usually represented the country at continental level. This period was marked by the appearance of first major international successes on club level. Serbian clubs made the best results, along with Croatian Dinamo Zagreb. The first to make a way to European final was Dinamo Zagreb who lost the 1963 Inter-Cities Fairs Cup Final. The next was Partizan, who in 1966 reached the European Cup final, losing to Real Madrid by 2-1 after winning by 1-0 until the 70th minute. In the following season, Dinamo Zagreb became the first Yugoslav club to actually win a European title, by winning the 1966–67 Inter-Cities Fairs Cup. Then it was Red Star who reached the final of the 1978–79 UEFA Cup, but the actual cherry on the top of the cake was the conquest by Red Star of the 1990–91 European Cup becoming the European club champion, and subsequently the World champion after winning the 1991 Intercontinental Cup. Hajduk Split, OFK Belgrade and Radnički Niš also made impressive results by reaching the semi-finals in European competitions. Beside this, in this period the Mitropa Cup was won by Red Star (2x 1958 and 1968), Čelik Zenica (2x 1971 and 1972), Vojvodina (1977), Partizan (1978), Iskra Bugojno (1985) and Borac Banja Luka (1992). The Balkans Cup was won by Radnički Niš (1975), Dinamo Zagreb (1976), NK Rijeka (1978) and Velež Mostar (1981).
