After beginning professionally with hometown's PFC Pirin Blagoevgrad, Andonov made a name for himself at PFC CSKA Sofia, constantly being one of the first division topscorers, while also being instrumental in the club's 1992 league conquest.
From 1994–96, he had two unassuming spells abroad, in Spain and Germany (the latter being in the second level). Returning subsequently to CSKA, Andonov netted 18 times in only 25 matches, for another championship conquest. He retired in 2000 at the age of 33, after two seasons with neighbours PFC Lokomotiv Sofia and another spell in Germany, with lowly 1. FC Union Berlin.
Andonov gained five caps for Bulgaria and was picked for the squad at the 1994 FIFA World Cup, but did not leave the bench during the tournament in the United States as the national team finished in fourth position.
