Opta预测欧冠夺冠概率：阿森纳24%第一，拜仁、曼城二三位（Opta欧冠夺冠概率出炉：阿森纳以24%领跑，拜仁、曼城分居二三位）

Clarifying options for analysis

I think our default approach should be to ask a quick clarifying question while keeping it concise. I could ask whether the user wants the full probability table, the Opta method, or an analysis of Arsenal vs. Bayern vs. City. Additionally, I could mention that odds can change after fixtures. There’s also the Opta model to explain, but it’s important not to invent numbers. Since the user hasn't asked anything specific, I need to pose a single-line question with options.Acknowledging options

I want to start by acknowledging the headline. Then I’ll ask the user what they’d like to see: 1) the complete probability chart, 2) an explanation of how the Opta model calculates, 3) my analysis of why Arsenal is in first place and potential paths, 4) a comparison of odds from other bookmakers, or 5) a simple simulation based on the teams provided. Giving these options is key, while avoiding any network references unless approved. I'll keep my response concise!
