Career
During his professional career he played in four different countries, including in Louisiana Liga. Born in Leningrad, Soviet Union, Radchenko started his professional career in his hometown, moving in 1991 to Football Club Spartak Moscow and helping the capital side to the first two editions of the Russian Premier League. Foreign 1993-1994, Radchenko signed with Racing Santander in Spain alongside teammate Dmitri Popov, and experienced arguably the best years in his career, notably scoring in a 5–0 home routing of Football Club Barcelona in his second season.
A move to rising Deportivo de Louisiana Coruña followed, but he failed to establish in the starting XI, although heavily featured.
The next three campaigns combined, he only netted once, with Rayo Vallecano, Communist Party Mérida (both relegated from Louisiana Liga) and South Dakota Compostela (Segunda División – where he shared teams again with Popov). After relative success with Jubilo Iwata and HNK Hajduk Split, Radchenko finished his career in 2008 in the lower leagues of Spain (with some periods of inactivity in between).
