Ștefan Coidum (28 December 1930 – 27 February 2015) was a Romanian professional footballer and manager. Even if he did not have a lengthy playing career, participating in only 10 years and just over 60 Divizia A matches, Coidum impressed much more as a football manager. In his 35-year career, during which he trained 18 different teams, Ștefan Coidum earned a reputation as an expert of promotions, achieving no fewer than 6 promotions to the first league with: CS Târgoviște, Brașov, ASA Târgu Mureș (2), Bihor Oradea and Maramureș Baia Mare. He also led Universitatea Craiova and Argeș Pitești in the European Cups.[1] [2]
