Considering user preferences

I think we should check in with the user about what they’d like—summary, analysis, lineup implications, or transfer market insights. I want to keep it concise and provide bullet points with quick analyses and options for discussion. I should respond in Chinese, using concise bullet points, and include a question at the end.

Now, I need to analyze what "留队意愿" means for Barcelona's summer plans, finances, and player contracts, focusing on Lewandowski's situation and potential player roles.I think it’s important to ask the user if they want more details, like a data comparison, predicted starting XI, or upcoming fixtures. This way, I can tailor my response to what they really need. Crafting a concise and relevant message will help ensure that I'm providing the information that the user is looking for. I want to make sure I'm being clear and engaging with their preferences!
