Clarifying user request
The user sent a message in Chinese mentioning Real Madrid's history in the Champions League, specifically noting they've only failed to reach the round of 16 once in 63 years. It seems like a statement or headline. I’m not quite sure what the user wants—maybe they’re looking for more information, an analysis, or contextual stats. Since the guidelines encourage being concise, I would consider providing context about their performance, including the seasons they didn’t advance.Considering Real Madrid's history

I’m realizing that in 2020, Real Madrid did advance, and they even won in 2022. The European Cup before 1992 didn’t have a group stage, and the round of 16 refers to the knockout phase. The statement from the user might be referencing Real Madrid's history, indicating they’ve missed the round of 16 only once in 63 seasons. However, I should clarify this, as it seems a bit off. I should ask if the user needs a translation, summary, or a full article.Clarifying user intent
The user’s one-liner looks like a headline, and they might want to turn it into a short news piece or some betting analysis. I should ask what they want me to do with it—are they looking for a translation, a rewrite, or maybe some background and key stats? Since I also want to keep it brief, I could ask if they want a quick stat breakdown, historical context, or a probability model. However, I'll need some context about the opponent and season to provide relevant info.Providing general info and clarification
I want to keep my response neutral while clarifying Real Madrid's Champions League performance. They’ve consistently advanced to the knockout stage since 1997-98, with a long streak up to 2019-20, and they even reached it in 2020-21. However, they failed to qualify in 1996-97. The Chinese phrase about "only once in 63 years" seems off, so I should avoid making assumptions. It’s better to ask the user for the specific season or match. I could also offer to turn this into a brief preview with supporting data.Offering options and asking for details
I want to help the user by asking them to share the opponent and season for better context. Alternatively, I can provide a generic template with typical supporting metrics. I could offer a few options: I could write a 200-word news preview in Chinese, provide bullet points with data supporting a win or qualification, or create a quick probability estimate using an Elo model if they give me the teams. I’ll craft a concise response in Chinese and suggest these options.

这是个标题式结论。你希望我做哪种输出?
- 写一篇短评/赛前前瞻(200-300字),用数据论证皇马赢球晋级
- 列要点式数据支持(近况、对赛往绩、主客场/进失球、出线形势)
- 粗算胜平负概率(用简单 Elo/Poisson),给出晋级概率
