Hyunjun Yang, born in South Korea on 25 May 2002 (age 24), came through at Gangwon FC before Celtic moved for him in July 2023. The fee was around £2m, a reasonable punt on a quick right winger who had already shown he could produce in the K League. His best league season in Korea came in 2022, with eight goals in 36 appearances for Gangwon.
Celtic has become the main body of his career. Wearing squad number 13, Yang has made 83 league appearances and scored 16 league goals across four seasons, while learning the more awkward parts of playing wide in Glasgow: less space, more expectation, and very little patience for decoration without output.
He has collected plenty in that time too. Yang has won two Premiership titles with Celtic, in 2024/25 and 2025/26, along with the 2024/25 League Cup and a Scottish Cup. He has also been part of a Celtic side that finished Scottish Cup runners-up once.
In 2026/27, he has made five league appearances and scored twice, with further outings in the Scottish Cup and Champions League qualifiers taking him to 11 Celtic appearances and two goals across all competitions for the season. He has also been involved with Korea Republic, featuring in World Cup and Asian World Cup qualifying matches. His current market value is around £4.5m, according to Transfermarkt.
Yang remains a current Celtic player whose career is now measured largely by what he does in green and white. He arrived as a developing wide player from Gangwon, has already played a meaningful part in trophy-winning squads, and is still in the stage where his next step has to be consistency rather than promise.
