ألمانيا vs الأرجنتين

In the second half of extra time (~108′, 0–0), Sergio Agüero caught Bastian Schweinsteiger flush in the face with a raised/swinging arm during a challenge, opening a cut that bled heavily. Referee Nicola Rizzoli gave nothing. The decisive fact: Agüero was already on a yellow card. So even the most lenient defensible reading — a reckless arm to the head = caution — produces a second yellow and a sending-off. And there's a strong argument it was a straight red for excessive force. Either route ends the same way: Argentina should have finished extra time with ten men.
