A. Trajkovic

Aleksa Trajković came through the youth system at Duel Juniors in his native Kruševac before moves to the academies of OFK Beograd and Jagodina broadened his development. He joined Spartak Ždrepčeva Krv's youth setup in 2024 and signed his first professional contract that December.

The attacking midfielder made his senior debut for Spartak Subotica on 2 August 2025 against TSC. He finished the 2025/26 season with three goals and an assist in the Serbian SuperLiga among his senior appearances that campaign. The club's relegation did not slow him down: in the Prva Liga that followed, Trajković continued to feature regularly and added to his goal tally.

At international level, Trajković has been capped by Serbia's under-19 side, taking part in qualifiers and finals of the UEFA European Under-19 Championship. He has not yet been called up to the senior national team.

Supporters searching his name online should take care not to confuse him with the defender Aleksandar Trajković, a different player altogether who built his career at clubs including Radnički Niš and won a Kazakhstan Cup — a career with no connection to the young Spartak Subotica midfielder's path.
