In a jaw-dropping finale that defied belief, the defending champions scored three times in the final 15 minutes to break Egyptian hearts and keep their World Cup dream alive with a staggering 3-2 victory.
Egypt had done everything right. Yasser Ibrahim headed them ahead inside 15 minutes.
Mostafa Zico made it 2-0 in the 67th. And goalkeeper Mostafa Shobeir was having the game of his life, even saving a Lionel Messi penalty in the first half.
But champions never say die.
Cristian Romero powered home a header.
Messi made amends from close range. And Enzo Fernández sent 80,000 fans into orbit with a 93rd-minute winner that will go down in World Cup folklore.
Messi now has eight goals in this tournament, and a place in history as the first man to score in six straight knockout matches.
Egypt? They leave with pride. Argentina? They live to fight another day.
