There were tears streaming down Son Heung-min's face at the Education City Stadium.
He wasn't the only South Korean crying. Several of his team-mates, and hundreds of their compatriots in the stands, had been reduced to an emotional mess by the most dramatic of finales to Group H, with the Taegeuk Warriors defeating Portugal with an injury-time winner from Hwang Hee-Chan to pip Uruguay to second place on goal difference.
The Koreans appeared to be going out with a whimper after conceding an early goal to Ricardo Horta. It was the worst possible start, and yet they responded in the best possible way, with Kim Young-Gwon pouncing on a corner that deflected off Cristiano Ronaldo to level the game before Hwang Hee-Chan popped up with an injury-time winner after a stunning surge from Son.
As for Portugal, they still progressed as group winners, meaning they have avoided Brazil but this was a game that raised more questions over Cristiano Ronaldo's fitness after a miserable evening for the forward.
