Lee Min-sung was the hidden culprit who ruined the 1998 World Cup match against Mexico..

‌Ha Seok-ju being sent off for a back tackle less than 5 minutes after scoring a free-kick goal was the decisive reason for the loss against Mexico.
But before Ha Seok-ju scored... Lee Min-sung had already received a yellow card for a back tackle...
The intensity of Lee Min-sung's back tackle was even more severe than Ha Seok-ju's, so there would have been no argument if he had been sent off according to the rules.
To be honest, the referee let it slide...
Ha Seok-ju's back tackle was somewhat clumsy... but because the referee had let Lee Min-sung slide earlier,
he didn't let it slide this time and issued an immediate red card.
If Lee Min-sung hadn't committed that back tackle... there was a high possibility that Ha Seok-ju would have only received a yellow card...
The one who ruined the match against Mexico wasn't Ha Seok-ju, but Lee Min-sung..
