During the last years before the break-up of Yugoslavia, football was experiencing much popularity throughout the country, specially because of the series of successes. Such were Yugoslavia winning the 1987 FIFA World Youth Championship, being runners-up at the 1990 UEFA European Under-21 Championship, an emotional campaign by the senior team in the 1990 FIFA World Cup in which Yugoslavia officially finished 5th after eliminating Spain in 1/8 finals, but losing dramatically in quarters against Argentina on penalties, a Red Star Belgrade winning of the 1990–91 European Cup and the 1991 Intercontinental Cup, and even the local Republika Srpska major club, FK Borac Banja Luka, won the 1992 Mitropa Cup. Football was always the most popular sport in all of Bosnia and Herzegovina, and those results had especially warm reception among Serbs in Bosnia because Yugoslav national team was known for having in Bosnia its strongest percentages of supporters, Red Star Belgrade was highly popular among Bosnian Serbs, and the conquest of Mitropa Cup in 1992 by Borac was the first ever international trophy won by a Bosnian team.
