In the summer of 1982 Belodedici was signed by FC Steaua Bucureşti, being selected by the club's chairman Ion Alecsandrescu, who was in search for a high quality sweeper.
Belodedici helped Steaua become the first Romanian - and Eastern Europe - club to win the European Cup in 1985-86, playing the full 120 minutes in the final against FC Barcelona in Seville.
