Proposing verification and analysis options

I think it’s best to avoid stating facts outright and instead ask if they want me to verify and summarize the article. Given that the language is Chinese, I can respond in Chinese and say something like: "我暂时没有该新闻的细节来源。如果你给我链接，我可以帮你快速梳理要点、过往战绩、解读影响；或者我可以直接联网查证最新消息."

I can also mention analysis angles like previous results and tactical issues, while emphasizing brevity and clarity.Offering options for assistance

I’m thinking of providing three options for the user:

1. They can send me a link, and I’ll summarize key points and relevant information.
2. I can search online and compile sources with verified details.
3. Alternatively, I can provide a framework of Costa Rica's recent performance, a list of potential coaching candidates, and an analysis of the impacts of a coaching change without connecting to the internet.

These options should help meet their needs!
