Paris Saint-Germain vs Arsenal

Referee Daniel Siebert correctly awarded a penalty to Paris Saint-Germain after Arsenal's #3 made contact with PSG's #7 from behind/side, causing the PSG player to go to ground inside the penalty area — the frames show clear physical contact rather than a clean ball-winning challenge, justifying the spot-kick. However, the decision was incomplete: the foul was reckless in nature (significant momentum, use of the body from behind), which under Law 12 should have also been punished with a yellow card. The submitter confirms Arsenal #3 was already carrying a yellow card from earlier in the match, meaning a second yellow card here should have led to a red card and a sending-off. The referee gave PSG the penalty but left #3 on the pitch — a significant missed sanction in a Champions League Final.
