Lee Young-jun

On 29 July 2024, Lee signed a four-year contract with Swiss Super League side Grasshopper. On 24 August, he scored within 44 seconds in a 3–1 victory over Sion, where he made his debut. On 27 May 2025, he scored the opener in the relegation play-off first leg against Aarau. Grasshopper avoided relegation after defeating Aarau 4–1 on aggregate. During the 2025–26 season, Lee made only 15 league appearances due to a long-term injury. The club once again faced Aarau in the relegation play-off. In the play-off second leg, he provided an assist for Lovro Zvonarek's opener, but was sent off in the 88th minute for kneeing Leon Frokaj in the face. Grasshopper won 2–1 after extra time, and he apologized to his team and fans on Instagram.

Lee played for the South Korean national under-20 team in the 2023 FIFA U-20 World Cup. He scored against France and Ecuador while helping his team reach the semi-finals. On 26 March 2024, Lee scored South Korea's first goal in the 2024 WAFF U-23 Championship final, where South Korea defeated Australia on penalties. Lee led South Korea to the quarter-finals with he scoring three goals in the 2024 AFC U-23 Asian Cup, but he was sent off for his unsportsmanlike foul in the quarter-final match against Indonesia, where South Korea was eliminated.
