Yugoslavia until the end of 1968, as transfers abroad were prohibited for players under 28 at the time. In December 1968, he went to the Netherlands, to play for Zwolsche Boys. This stay lasted only three months, due to a knee injury. In 1970, Osim signed with Strasbourg and played the rest of his career in France, playing also for Valenciennes, Sedan and again at Strasbourg. International career Osim made his debut for Yugoslavia in an October 1964 Olympic Games match against Morocco, and has earned a total of 16 caps, scoring eight goals. He also played at UEFA Euro 1968 where Yugoslavia reached the final, losing to Italy. Osim's final international game was an April 1969 World Cup qualification match away against Spain. Managerial career Željezničar When his playing career ended in 1978, Osim took the managing job at the club where he began playing, Željezničar. He managed the club until 1986, and finished third in the Yugoslav championship once, reached the Yugoslav Cup final once and the UEFA Cup semi-finals once. Yugoslavia Osim assisted Ivan Toplak, head coach of the Yugoslav Olympic team, at the 1984 Summer Olympics where Yugoslavia won the bronze medal. In 1986, he took over the Yugoslav national team. The first qualifying cycle for UEFA Euro 1988 ended in failure with an embarrassing 1–4 home loss against England. Contrary to expectations and custom considering the fate of Yugoslav head coaches who presided over prior failed qualifying campaigns, Osim was not fired by the Yugoslav FA largely thanks to personal authority of FA president Miljan Miljanić who wanted Osim to be given another chance. Osim's Yugoslavia rebounded in the 1990 FIFA World Cup qualification, finishing ahead of France and Scotland. At the 1990 FIFA World Cup, Yugoslavia reached the quarter-finals by eliminating Spain 2–1 in the round of 16, and proceeded to face Diego Maradona's Argentina in the quarter-finals. Despite losing a defender, Refik Šabanadžović, to a red card at the half an hour mark, Osim's team held on through the entire game and extra time, only to lose on penalties. Yugoslavia qualified for UEFA Euro 1992, but Osim resigned on 23 May 1992; as his family in Sarajevo faced bombardment during the Bosnian War. "My country doesn't deserve to play in the European Championship," said Osim, "On the scale of human suffering, I cannot reconcile events at home with my position as national manager."
