Clarifying user intent

I'm wondering what the user wants—are they looking for a fact-check or a source? It’s important for me to confirm their intention before providing a response. I should suggest a quick fact-check while letting them know about the limitations on browsing. I don't want to assert anything incorrectly, so asking a clarifying question seems wise. If they want verification, I could check with Opta or UEFA and provide some general knowledge too. Additionally, mentioning specifics like "11" and Barcelona's own goals could be useful!Asking for clarification

I'm thinking about how to ask the user if they want me to fact-check, find a source, or do a data comparison. There's a bit of ambiguity around "own goals," especially since it could imply different things. My understanding is that when people say “most own goals,” they often mean benefiting from them rather than making them. Also, Barcelona has had several own goals, possibly totaling around 11 between 1992 and 2024, but to avoid spreading misinformation, I should suggest verifying this. I'll keep my final answer structure minimal!Offering clarification options

I'm considering providing two possible correct statements. One could say that if it refers to “benefiting from opponents' own goals,” Barcelona is indeed high on that list with around 10 or more goals—yet the exact ranking might depend on the specific stats. The other statement could focus on “own goals scored,” where Barcelona might also be around 10, close to the top. It feels a bit vague, so I think it’s wise to ask if the user wants me to verify and list each goal and source, but I might need approval for web access.
