Vâlcov was part of the famous offensive line of Venus Bucureşti in the 1930s, together with his brothers, Petea and Volodea. He was arguably the most talented of the three, with a great header (his most feared weapon) and good anticipation in front of the goal.
The three brothers, originally from Moldova, are included in the list of the greatest football players in the history of club football Venus Bucureşti.
Two of his brothers had final tragics. First, Petea died on the front in 1943 World War II, on the eastern front, fighting the Soviets, And almost over a decade, Volodea left this world due to tuberculosis. Senior Colea was the most longevity. Once after his footballer career, he became a coach for Romania, Steaua Bucureşti and Dinamo Bucureşti.
He is the second manager in the history of Steaua Bucureşti.
