拉美媒体：拜仁、曼联、马竞追逐厄瓜多尔17岁中场卡斯蒂略（拉媒：拜仁、曼联与马竞竞逐厄瓜多尔17岁中场新星卡斯蒂略）
Crafting a news brief
I’m thinking about responding with a concise news brief that mentions it’s being reported by Latin American outlets, noting that there aren’t any official bids yet. The player in question is a 17-year-old Ecuadorian midfielder named Castillo. I’ll acknowledge this is just a rumor and ask for more specifics like his full name or club. I can offer a short template with context on transfer rules and possible fees, and check sources if they provide a link. Also, I’m considering the sandbox setup for web searching.Planning the response
I'm considering that the CLI harness might not allow web browsing via curl; however, I can use shell and network options. It’s probably best to ask the user if they want me to look up sources. Following the "Ask only when needed" guideline, I can keep it casual with a one-liner style.
I'll summarize the rumor briefly, ask which Castillo they mean, and offer to verify through sources or write a quick news brief. I'll also create a concise message in Chinese while keeping it brief.
这像是转会流言的标题。先确认下信息：能提供这位“卡斯蒂略”的全名或现俱乐部吗？厄瓜多尔同姓球员不少，避免认错人我再给你更准确的背景与评估。
快速背景与可行性
- 权威程度：目前看属于拉媒报道层级，尚无官宣或一线转会记者背书，可信度待核。 
- 年龄与规则：17岁从南美转去欧洲普遍受FIFA未成年人限制；英超（曼联）基本需等到18岁才能注册，西甲（马竞）同样受限，通常是“先签后到”或预协议。
- 操作路径：常见为固定转会费+浮动+二转分成；以同档案例（如帕埃斯）参考区间大致在千万欧以内到约两千万欧含浮动，视潜力与出场数据浮动。
- 去向适配：拜仁多先进入U19/二队再过渡一线；英超需等待注册生效并可能先外租；马竞亦可能先融入青训/预备队体系。
需要的话我可以：
- 帮你核实具体报道和来源，并做可信度分级；
- 整理球员球探档案（位置、脚型、数据、风格、对比模板）；
- 写一条简短快讯稿或社媒帖文。
