One of Steaua București's greatest players, Iordănescu was a forward or attacking midfielder with a well-developed scoring technique and uncommon dribbling ability. He was also well known for his vision and set-piece ability. In Romania, he played only for Steaua, a team he joined as a youth in 1962, aged 12. Six years later, he made his debut for the first team, followed by his first appearance for the Romania national team in 1971. During this period, he scored 155 goals, becoming the team's highest ever goalscorer.
