最佳结局，布斯克茨以美职联总冠军身份结束17年职业生涯（完美谢幕：布斯克茨捧美职联总冠军后结束17年职业生涯）

Considering how to assist

It's tricky to verify information, plus we need to avoid spreading misinformation. My best guess is to acknowledge the sentiment first and then ask clarifying questions or discussed aspects of Busquets' legacy, regardless of the current news. I could suggest various options to the user, like whether they’d like a short news piece, a social media post, or a summary of career highlights in Chinese. Keeping it concise and clear would be ideal!Crafting a response cautiously

I need to be careful not to definitively claim information. Instead, I could phrase it as "如果这是官宣/据报道" or ask for the source and timing. If the user wants a social media post or a short review, I can offer different versions. I should make sure to provide both a news version and a more emotional one, while keeping details generic to avoid assumptions about specific events. Including a compact honors list of Busquets’ career milestones would be helpful too!Summarizing key highlights cautiously

I think I need to prepare social media posts in two different styles and create a bullet list of Busquets' career highlights and major honors. He has made 722 appearances for Barcelona, but to be safe, I should phrase it as "出场700+". For his championships, I know he won 3 UEFA Champions League titles, 9 La Liga titles, and 7 Copa del Rey titles. It’s best to stick to general phrasing to avoid errors, like "3次欧冠、9次西甲、世界杯+欧洲杯各1次."Structuring key highlights and options

I’m thinking of including only solid achievements for Busquets, like 3 UEFA Champions League titles, the World Cup in 2010, and the Euro in 2012—while avoiding exact counts on Liga titles by saying "多次西甲." For defining characteristics, I could mention his positioning, rhythm control, and partnerships with Messi, Xavi, and Iniesta. To wrap it up, I’ll ask if the user wants a detailed review or a video script. I'll prepare options in Chinese with clear bullet points and stick to concise formatting.
