想要哪一份“已官宣完成”的转会清单？请帮我确定几项就能马上整理：

Clarifying user request

\n

I need to respond to a Chinese user asking for a list of completed football transfer deals. Since the user's query lacks specific details like the league, transfer window, or year, I should clarify what exactly they're interested in. They might want information on the Chinese Super League or one of the top five European leagues. Asking for specifics like the club or region would help me provide a more precise answer. Alternatively, I could suggest typical sources for this information.Proposing user options

I think I should propose a summary of the latest transfer window for the top five leagues. However, since it's currently December 29, 2025, the winter transfer window has just opened, and there might not be many completed deals yet. Without access, I can't provide exact details, so I should clarify the user's needs first. I can ask them which season or league they're interested in, whether they want only official announcements, and their preferred format. If they don't specify, I could give a default summary of recent transfers in the last seven days. Also, I could mention potential sources like Transfermarkt and Fabrizio Romano if they allow network access.Creating a concise question list

I think I should create a clear list of questions with options for the user regarding the transfer window. First, I’ll ask them to choose the season and window, like the 2025 summer window or the 2026 winter window, considering it is currently December 29, 2025. Next, I’ll inquire about the scope: whether they're interested in global transfers, a specific league, or a particular club. I can offer options like preferred fields (player, age, position, etc.) and desired output formats such as chat summary, CSV, or JSON. Finally, I can suggest specifying the timeframe for the data. Keeping this concise with 4-6 bullets will be important!
