Creiniceanu was born on 1 February 1939 in
Lupeni, Romania and began playing junior-level football in 1959 at local club
Minerul. In 1957 he started to play for the seniors, helping them gain first league promotion at the end of the
1958–59 Divizia B season. In 1961, Creiniceanu joined
Steaua București where he won six
Cupa României, but played in only two of the finals, which were both 2–1 victories against
rivals Dinamo București. During these years, he also scored two goals in the derby against Dinamo, of which the first was in the 5–3 defeat in the
1964 Cupa României final and the second was in a 3–2 league loss. The team also won the
1967–68 title under coach
Ștefan Kovács, but Creiniceanu did not make a single league appearance during that season. During his spell with
The Military Men, Creiniceanu made his only eight appearances in European competitions. He also scored a goal in the 5–3 aggregate loss to
Spartak Trnava in the first round of the
1968–69 European Cup. On 22 July 1970, he made his last Divizia A appearance in Steaua's 1–1 draw against
Bihor Oradea, totaling 207 matches with 65 goals in the competition. ==International career==
