In the 2002 FIFA World Cup, Argentina and Nigeria were both drawn into Group F; Argentina won 1–0, a result that was repeated in 2010.

As group winners, Argentina advanced to face Mexico, the Group A runners-up, while Korea Republic, who finished as group runners-up, faced Uruguay, who won Group A.
