Jedinstvo Ub

Ub is a small town in the Kolubara District of western Serbia.

The closest it came to disappearing was in 2016, when Jedinstvo dropped into the Drina Zone League, the fourth level of the pyramid.

What followed was the fastest climb in the club's history. In June 2022, Jedinstvo was administratively promoted to the First League of Serbia after Žarkovo vacated its place. Two seasons later, a second-place finish in that division sent the club into the Serbian SuperLiga for the first time. The stay lasted one season: a 16th-place finish in 2024/25 sent Jedinstvo straight back down to the First League.

Domestic cup football gave the club its biggest occasion yet. In 2025/26, Jedinstvo reached the semi-final of the Serbian Cup, a round it had never reached before, and drew Crvena Zvezda, the Belgrade club it had once partnered with as a youth-development affiliate back in the late 1990s. A team from a stadium holding 4,000 people, named after Dragan Džajić, faced the club whose academy once trained its own young players.
