In that period the club had difficulties in finding opponents as there were not many existing clubs to play against, so one of the first and the biggest public matches at that period was played among two teams of SK Soko on "St. George´s Day" (Đurđevdan), on May 6, 1904, in the honour of the celebration of the centenary of the First Serbian uprising. In that match (the score is unknown) following players participated: Stevan Stefanović, Milan Bajić, Vladimir Skobla, Dimitrije Đorđević Piperski, Dimitrije Stamenković, Nikola Spasić, Hugo Buli, Vlada Krstić among others. Six months after the club's foundation, Serbian football and engineering pioneer, Danilo Stojanović–Čika Dača, on 14 September 1903, founded the football club Šumadija so Soko got their first domestic rival.
