Former Bundesliga referee Greif gave an interview to Kickers, discussing Embolo's red card.

Talk about Embolo getting a red card

"How could a player be so clumsy? With a yellow card already in hand, he tried to cheat like that—and near the sideline no less… It was just too awful."

"This 'identity confusion' procedure itself violates the established rules. The rule is intended to correct errors in showing red and yellow cards to the wrong players—not to interchange penalties for such behavior...nor to overturn erroneous decisions based on factual findings."

"Argentina is strong enough that they could probably win even without these factors."
