During his career, he represented mainly Sporting in Portugal, appearing in more than 250 official games in one full decade and winning two major titles.
Born in Samokov, Yordanov began his career at local PFC Rilski Sportist, where he first appeared professionally at not yet 15, moving to FC Lokomotiv Gorna Oryahovitsa in 1989. In the last of his two seasons, he topped the first division scoring charts, at 21 goals, helping lowly Lokomotiv to a comfortable ninth place.
In 1991–92, Yordanov joined Sporting Clube de Portugal, signing alongside compatriot Boncho Genchev – who had been his predecessor at Lokomotiv GO – where he would play in a variety of positions (including central defender, due to injuries to teammates). Persistent injury problems and multiple sclerosis led to a 2001 retirement, still with the Lisbon club (he contributed with 11 matches and one goal in the team's Primeira Liga conquest the previous year).
In the former, in another display of "team-first" attitude – and first discovering his versatile qualities – during the round-of-16 contest against Mexico (as Bulgaria prevailed in a penalty shootout) he filled in at stopper, due to the absence of Trifon Ivanov (suspension) and Nikolay Iliev (injury). During the match, he set up Hristo Stoichkov's goal in the 1–1 draw.
Yordanov would also appear at UEFA Euro 1996, playing all three group stage matches (two complete) as Bulgaria finished third in its group.
