Born on March 20, 1998, the 27-year-old is 173 cm tall and embodies the modern full-back who is as much a weapon in attack as he is in defense. His rise through the ranks was accelerated by his explosive speed and crossing ability, eventually earning him a move to the K League 1 giants Ulsan. Here, he has been part of a squad that has challenged for and won domestic titles, contributing assists and defensive cover in equal measure. Valued at €450,000, his performances have also put him in contention for national team recognition. Yoon's game is defined by his marauding runs and ability to beat his marker, making him a constant outlet and a nightmare for opposing wingers. He is a prime example of the evolution of the full-back position in contemporary football.
