Usce U19

Founded in 1934 in Stepojevac, the side was known in turn as Vita Petrović, Posavina, 7. Oktobar, Stepojevac and Stepojevac Vaga before it settled on FK Ušće Novi Beograd in 2021.

The results came in a steady climb through the Belgrade district pyramid: the Belgrade 2nd League in 2012–13, the 1st League a year later, the Belgrade Zone League in 2014–15. Each step raised the level of opposition without changing much else about the club. Then, in 2024–25, Ušće won the Serbian League Belgrade and went up to the Serbian First League for the first time in its history — a promotion nine decades in the making, reached only after the club had already changed its name five times. The stay was brief: a 16th-place finish sent them back down for the 2026–27 season, returning to the third tier they had just left.

The U19 side now competes in the Serbian U19 League, and the derbies it plays against FK Teleoptik Zemun, FK Radnički Obrenovac and FK BASK TEK carry the weight of a rivalry built up over years in the same regional divisions rather than a single famous fixture. The club wears red and white and has done through every one of its name changes.

Home games are played at the Stadium of FK IMT, an arena in New Belgrade also known as the Old Traktor Arena, standing near the Ranke Žeravica Sports Hall and holding 1,150 people — a small ground for a club that spent a season, at least, in the second tier of Serbian football.
