In June 1979, Sušić scored his second international hat-trick as Yugoslavia beat Italy 4–1 in a friendly match held in Zagreb. In September, he again scored three times in a 4–2 win over world champions Argentina. Sušić was a member of the Yugoslav team that qualified for the 1982 FIFA World Cup, scoring once in a 5–0 win against Luxembourg. Sušić was top scorer of Yugoslavia in qualification for UEFA Euro 1984. His two goals in a 3–2 win over Bulgaria in the final qualification fixture helped Yugoslavia to finish three points ahead of the Bulgarians and one point ahead of Wales and advance to the tournament finals. Yugoslavia ultimately finished bottom of their group in France, losing all three matches. At the age of 35, Sušić made his second appearance at a World Cup finals as a member of Yugoslavia's squad for the 1990 FIFA World Cup in Italy. He scored his only World Cup goal in the team's 4–1 win against the United Arab Emirates during the group stage. He played 61 minutes before being substituted for Dejan Savićević in the penalty shootout loss to eventual runners-up Argentina at the quarter-final stage. In 2004, to celebrate UEFA's Jubilee, Sušić was selected as the Golden Player of Bosnia and Herzegovina by the Football Association of Bosnia and Herzegovina as their most outstanding player of the past 50 years. His former international teammate, Darko Pančev declared:   Sušić first managed French club Cannes during the 1994–95 season and the beginning of the 1995–96. From 1996 until 1999, he managed İstanbulspor, then Al Hilal in 2001, Konyaspor from 2004 to 2005, Ankaragücü from 2005 until 2006, Çaykur Rizespor on two occasions, first in 2006 and the second time from 2007 to 2008. Sušić was then hired by Ankaraspor (today known as "Osmanlıspor") in March 2008. He left Ankaraspor in June 2008. On 28 December 2009, Sušić was named head coach of the Bosnia and Herzegovina national team. His debut was a friendly match against Ghana in Sarajevo. Bosnia and Herzegovina won the game 2–1 after goals from Vedad Ibišević and Miralem Pjanić.
