Jagiellonia Białystok are nearing the signing of Aleksandar Ćirković, a Serbian player for the Hungarian club Ferencvárosi TC. A report mentioned that the team from Chorten Arena had been considering the Serbian player for some time, as he is leaving his current team. Górnik Zabrze also became interested in signing the winger, who spent the previous season with Lechia Gdańsk. However, Jagiellonia could offer European football, which Górnik Zabrze could not guarantee. For this reason, it is reported that the 24-year-old decided to accept the offer from Jagiellonia Białystok. Ćirković joined Ferencváros in January 2025, and his contract is valid until the end of 2027. His current Transfermarkt market value is €2.00m.
