💼 Career

Um Won-sang signed his first professional contract with his hometown club, Gwangju FC, in 2019. He made an immediate impact during his rookie season, helping the club secure the K League 2 title and promotion to the top flight. In 2020, he established himself as a regular starter in the K League 1, utilizing his blistering pace to score seven goals and emerge as one of the most exciting young wingers in South Korea.

His sensational form earned him a high-profile transfer to K League 1 giants Ulsan Hyundai (now Ulsan HD) ahead of the 2022 season. Um enjoyed a career-best campaign in 2022, scoring 12 league goals and helping Ulsan secure the championship. His exceptional contributions earned him a spot on the K League 1 Best XI. He continued to play a vital role as Ulsan won three consecutive league titles from 2022 to 2024.

However, the 2025 season proved challenging for the speedy winger. Hobbled by persistent knee injuries, he struggled to find his peak form, managing only one goal in 30 appearances as Ulsan unexpectedly slumped in the standings. Recognizing the need for a mutual change, Ulsan HD announced his departure in early 2026 as part of a massive squad overhaul.

Seeking to rejuvenate his career, Um signed with Daejeon Hana Citizen for the 2026 season. Taking the number 11 shirt, he was tasked with injecting pace and creativity into the Daejeon attack. Fully recovered from his knee issues, he is highly motivated to prove that he remains one of the fastest and most dangerous wingers in Asian football.

Internationally, Um represented South Korea at the 2019 FIFA U-20 World Cup, helping the team reach the final. He made his senior debut in 2020 and won a Gold Medal at the 2022 Asian Games (held in 2023), securing military exemption. Heading into the 2026 FIFA World Cup cycle, his unrivaled speed makes him a highly valued tactical option for the national team.
