As part of FCSB's new strategy to scout for affordable young talent in Portugal and South America, Mihai Stoica travelled to Portugal to observe players ahead of the winter transfer window. Information from Sport.ro indicates that the club official attended the Paços de Ferreira versus Portimonense match. The source also reported that while he was there to watch several players, he was deeply impressed by Kauan Conceicao Ferreira da Silva, a 22-year-old Brazilian defender. Kauan came through the Red Bull Bragantino academy and is a versatile player capable of performing as both a central defender and a defensive midfielder, which is a profile the club's owner has been seeking. He joined Portuguese top-flight team Santa Clara on a free transfer in 2023 but has since been loaned to lower-league sides, becoming a key player for his current club, Paços de Ferreira. Kauan's contract with Santa Clara is until the summer of 2026, and his loan expires in June 2026. Transfermarkt estimates his market value to be approximately 60,000 euros.
