Summarizing transfer details
I want to provide a crisp summary and suggest next steps. If the user likes, I can track credible sources or give a timeline for the Chinese Super League winter transfer window. I plan to provide lightweight analysis on why deals can't be finalized, like league access restrictions and medicals. Responding in Chinese seems fitting. I could follow a bullet-point style for clarity. Let's include key information without running commands, keeping it concise.
要点：
- 目前只是传闻。于根伟明确表态：现在不可能敲定引援，别轻信消息。
- 这通常意味着：转会窗、准入/注册、预算与名额、体检签约等环节尚未到位，俱乐部不便提前确认。
- 真有进展一般会有信号：俱乐部官宣、公示的注册名单、媒体合照/体检目击、多家权威媒体同向报道。 
- 建议只参考：俱乐部官微/官网、中国足协/职业联盟公示、主流记者与本地媒体。一些“截屏流”“内部人士”多为伪造或拼接。
需要的话我可以：
- 跟踪权威渠道，有实锤再提醒你；
- 简述本赛季津门虎外援名额/位置需求与引援策略；
- 帮你筛一批可靠记者/媒体账号方便关注。
