裁判专家：罗德里戈踢对方脚后跟，应该被罚下（裁判专家称罗德里戈踢到对手脚后跟，理应被罚下）

Clarifying red card criteria

I want to provide a general breakdown of what could lead to a red card during a match. Although I can't give definitive claims, I'll include options for quick reference, like a checklist of criteria.

First, I should clarify the specifics of which match we're discussing. I'll explain the common offense types and various considerations, such as the point of contact and intensity of the foul.

I can touch on the sanctions involved, the VAR protocol, and mention precedents, but I'll keep it concise and even reply in Chinese!I want to provide clear options for the user in a polite and concise manner. I can share a clip or offer to break it down frame-by-frame if that’s what they prefer. Alternatively, I could give them a template to help structure an argument about the content. I’ll make sure to avoid heavy formatting so it’s easy to follow. Let's move forward with these next steps!
