About
UNNAK Sports is a Belgrade-based football representation business led by Nikola Kolarov, with a legal entity dating back to January 2012. The agency operates an unusually concentrated portfolio of five players, combining senior experience through Rade Krunić with some of Serbia’s strongest emerging talent, particularly Vasilije Kostov and Aleksej Vukićević.
Its history goes beyond its current roster. Official Serbian football records show Kolarov and Unnak Company involved in club-side transactions for Partizan and Red Star, while the current strategy appears strongly centred on high-upside Serbian talent and selective international exits, including Andrej Subotić’s move from Čukarički to the United States.
Key People
Nikola Kolarov – Owner / Director / Football Agent
Nikola Kolarov is the 100% owner and registered director of UNNAK SPORTS DOO BEOGRAD. He has operated in Serbian football representation for more than a decade, with official Serbian football records documenting intermediary activity involving clubs including Partizan and Red Star. More recent media coverage directly identifies him as the agent of Vasilije Kostov and Rade Krunić. Kolarov is also the brother of former Serbia captain Aleksandar Kolarov, a connection frequently referenced in 2026 media coverage surrounding reported Inter interest in Kostov.
Contact: nikola.kolarov@yahoo.com | +381 64 424 4392Srđan Karić – Former Agency Director / Scouting Executive
Srđan Karić became director of UNNAK Sports in November 2022 after previous scouting roles with LIAN Sports, Partizan and Red Star. In late 2023 he left for the role of academy director at FK Sarajevo, and later public professional records show him returning to Red Star in a youth-scouting capacity. He therefore appears relevant historically to UNNAK’s scouting development, but he is not listed as a current legal director of the company.Licensed agents

Notable former clients
No reliable historical player-client archive could be verified.
Historical Serbian football records show Unnak Company acting on the club side in Aleksandar Subić’s move from Borac Banja Luka to Partizan and Željko Gavrić’s transfer from Red Star to Ferencváros. These records demonstrate agency transaction activity but do not establish that Subić or Gavrić were personal representation clients.

Approach & Philosophy
UNNAK Sports appears to favour a highly selective portfolio rather than a high-volume representation model. Five players generate a €31.50m portfolio, with the majority of that value concentrated in a genuine elite prospect in Vasilije Kostov. The agency combines that high-upside youth work with experienced senior representation through Rade Krunić and established Serbian first-team players such as Nikola Stanković.
The pathways also show patience and flexibility. Kostov remained at Red Star for further senior development despite intense transfer speculation in 2026, while Subotić was moved abroad at 18 into the Charlotte FC development structure. Stanković’s return to Čukarički after one season at Red Star also suggests willingness to prioritise playing environment and role rather than simply keeping a player at the highest-profile club.
Fees & Transparency
UNNAK Sports does not publicly publish its current commission schedule, dual-representation policy, image-rights policy or player-expense policy.
There is historical transparency through Serbian football intermediary reports. In the 2015/16 period, Unnak Company received €9,000 for representing Partizan in Aleksandar Subić’s transfer, stated as below 3% of the transaction. In 2021/22, Nikola Kolarov / Unnak Company received €96,000 net for representing Red Star in Željko Gavrić’s transfer to Ferencváros.
Under the current FIFA Football Agent Regulations, football-agent services require a FIFA-licensed individual and a written representation agreement. FIFA’s published service-fee caps are 5% of remuneration up to USD 200,000 and 3% above it for an individual or engaging entity; 10% and 6% respectively for permitted dual representation of an individual and engaging entity; and 10% of transfer compensation for representation of the releasing entity. Dual representation requires advance written consent from both clients.
Compliance & Reputation
Disciplinary actions / sanctions: No public football disciplinary sanction against UNNAK Sports or Nikola Kolarov surfaced in the reviewed Serbian FA, corporate and football-media sources.
Litigation / disputes: No current court proceeding involving UNNAK SPORTS DOO was identified in the reviewed company records. The company is shown as active, without blocked accounts or recorded tax debt.
Corporate standing: The company received an A+ business-credit assessment for 2026. Reported 2025 revenue was RSD 55.12m with RSD 27.785m net profit.
Media sentiment: Positive / neutral. The agency itself keeps a relatively low profile, but attention around Vasilije Kostov has become significant. He was ranked No. 34 in NXGN 2026 and has been linked with Arsenal, Barcelona, Bayern Munich and several major Italian clubs.
Media scrutiny: Some 2026 transfer coverage highlighted the family relationship between Nikola Kolarov and Aleksandar Kolarov, who works within Inter’s football structure, while discussing potential Inter interest in Kostov. This was presented as a potential negotiating connection, not as an allegation of wrongdoing.
