The versatile 25-year-old, who can play on both the left and right sides of defence, broke into the Ulsan side in 2020 and was part of the squad that won the AFC Champions League later that year under Kim Do-hoon.
He was named the K League 1’s Young Player of the Year in 2021 and established himself as a key member of the Ulsan side that would go on to win the domestic league title in 2022 and 2023 under the guidance of Hong Myung-bo.
Seol made his debut for the national team in a friendly against El Salvador in June last year and featured for Korea Republic at the AFC Asian Cup Qatar 2023, when the Jurgen Klinsmann-coached team reached the semi-finals before losing to Jordan.
He becomes the second Korean player to sign for Red Star and joins international team mate Hwang In-beom, who moved to Belgrade in 2023 from Olympiacos. The club have won the Serbian title on 10 occasions, including the last seven in a row.
