The Korea Football Association has been revealed to have provided sexual entertainment to foreign referees during international matches from 2011 to 2012. During this period, the Korean national football team recorded undefeated results (5 wins and 2 draws) in matches officiated by these referees. Notably, they achieved victories under the judgment of referees who received such treatment in World Cup and Olympic qualifiers, successfully advancing to the finals. However, these actions are being criticized for violating the fairness of sports and are expected to significantly damage the image of Korean football. FIFA sanctions are likely to be difficult due to statute of limitations issues.
