The 1986–87 season was FC Dinamo București's 38th season in Divizia A. Mircea Lucescu begins the reconstruction of the team, with players from Dinamo own's yard (Ionuț Lupescu, Bogdan Stelea or Bogdan Bucur), but also with an important transfer campaign. Among others, in this season are brought Dănuț Lupu from Dunărea Galați, Dorin Mateuț from Corvinul and Rodion Cămătaru from Craiova. The latter will be the topscorer in the championship.
Dinamo finishes the season on the second place, but 15 points behind Steaua, who ends the season without a single loss. In the Romanian Cup, Dinamo loses the final, against the same Steaua. In Europe, Dinamo plays again after 18 years in the Cup Winner's Cup, but loses in the first round against Albanian team 17 Nentori Tirana.
Dinamo brought Ilie Balaci (FC Olt), Rodion Cămătaru (Univ. Craiova), Dorin Mateuț (Corvinul Hunedoara, in the winter break) and Dănuț Lupu (Dunărea Galați, in the winter break). Nelu Stănescu and Nistor Văidean were transferred to Flacăra Moreni (in the winter break). Stelea, Bogdan Bucur, Lupescu and Tene made their debuts.
