Um Ji-Sung

Um Ji-Sung made the step from Gwangju FC to Swansea City in 2024, joining a Championship club with a strong tradition of developing technically gifted midfielders. Composed in possession and intelligent in his movement, he represents the next generation of Korean midfield talent. Still only 24, his inclusion in the national squad reflects the coaching staff's willingness to blood younger players alongside the established European-based core. His time in Wales will have sharpened his understanding of pressing-oriented football. At this World Cup, he is likely to feature as a rotation option rather than a guaranteed starter, but his ceiling is high.
