Although it was just a "friendship" within the team, the Korean Football Association still worked hard on the details. This game will officially adopt VAR (Video Referee Assistant System), which is also a milestone moment in the history of Korean football. In the previous international A-level competitions held in South Korea, there is no precedent for using VAR. Although it is a special friendly match, the Korean Football Association still has high standards and strict requirements. For the players, this is no longer like a "confrontation match" within the team, but a battle that truly represents glory. As fans, they are also happy to see such a highly simulated battle in actual combat.
