South Korean national team full-back Seol Young-woo has officially completed his transfer to the German Bundesliga club FC Augsburg, sealing a major career milestone just two years after making his initial leap to European football. According to the announcement made by FC Augsburg on August 27, 2026, the versatile defender has signed a four-year contract that keeps him with the club until June 30, 2030. 

While both clubs chose to keep the exact financial details confidential, local media reports indicate that the transfer package—including various performance-related options—amounts to approximately €5.5 million (around 8.85 billion KRW). Additionally, his former club, Red Star Belgrade, has secured a 10% sell-on clause should Augsburg transfer Seol to another team in the future. In a rather unique and notable gesture for a defensive player, Augsburg has assigned him the prestigious number 7 jersey, signaling high expectations for his impact on the pitch. 

Seol’s journey to one of Europe’s top five leagues is a testament to his rapid development and consistent performances. A product of the youth system of Ulsan HD (formerly Ulsan Hyundai) in the K League 1, Seol made his professional breakthrough in 2020. During his time in domestic football, he established himself as one of the premier full-backs in South Korea, winning back-to-back K League 1 titles in 2022 and 2023, earning a spot in the K League 1 Best XI, and picking up a gold medal at the 2022 Hangzhou Asian Games which granted him military service exemption. 

In the summer of 2024, Seol took his first step abroad by joining Serbian powerhouse Red Star Belgrade. Despite the usual challenges of adapting to a foreign league, he experienced a seamless transition and quickly locked down the starting right-back position. Over two successful seasons in Serbia, Seol made 101 official appearances, contributing 8 goals and 16 assists while experiencing regular action in elite European competitions like the UEFA Champions League. His stellar defensive reliability and offensive contributions earned him a place in the Serbian SuperLiga Team of the Season for two consecutive years (2024–25 and 2025–26) and helped Red Star capture consecutive domestic doubles. 

On the international stage, Seol has steadily cemented his status as a core pillar for the South Korea national team. Having accumulated 37 A-international caps, he notably represented the Taeguk Warriors at the 2023 AFC Asian Cup and started all three group-stage matches for his country at the 2026 FIFA World Cup. Although the national team faced scrutiny following the World Cup campaign, Seol's relentless work rate, tactical flexibility, and ability to operate comfortably on both the right and left flanks continued to attract attention from scouts across Europe's top leagues. 

By moving to Augsburg, Seol becomes the fourth South Korean player to wear the club's uniform, following in the footsteps of legendary predecessors Koo Ja-cheol, Ji Dong-won, and Hong Jeong-호. Augsburg's sporting director, Benny Weber, welcomed the signing, highlighting that Seol's extensive experience in European club competitions and international matches will bring dynamic energy, speed, and heightened positional competition to the squad's flanks. 

Expressing his enthusiasm during his unveiling, Seol shared his thoughts on the new chapter of his career: "I am very much looking forward to my time at Augsburg. The Bundesliga is an excellent and highly competitive league. I want to prove myself here, demonstrate my capabilities, and continue to grow as a player." He added, "I am eager to perform in front of the home fans at the WWK Arena and give everything to help the team achieve its collective goals." 

Seol will have an immediate opportunity to integrate into the squad as FC Augsburg prepares to kick off their 2026–27 Bundesliga campaign with an opening match against FC Schalke 04. Fans and pundits alike will be watching closely to see how quickly the Korean full-back can translate his Balkan success onto the grand stage of German football.
