The Korean footballer in Argentina's lower division with his own sponsors on his jersey
This is Euihyeon Jung, who plays for Yupanqui in Argentina's Primera C.
This weekend, he debuted in the derby against Lugano wearing a different jersey from his teammates, promoting Café Seúl (a Korean restaurant in Buenos Aires) and Gangnam Express (a Korean goods store), while Yupanqui's regular jersey features Pinturerías Megaprint as the main sponsor.
This is part of a marketing initiative between the club and the sports committee of the Korean Association in Argentina, which was announced in March of this year when Jung joined Yupanqui.
