Considering Barça sale implications
It seems plausible that Barça is retaining 50% of any future sell-on fees, as some reports suggest. I should consider the tactical needs for clubs like Milan and Newcastle, who both require depth at RB/CB. I want to estimate market value, but I should avoid specific numbers without reliable sources.
I could ask the user if they'd like me to provide a full translation, context, player analysis, or verify recent information. Also, since the user wrote in Chinese, I should reply in Mandarin to keep it consistent!Crafting a Chinese response
I want to provide a translation to English as an option, but since the user offered content in Chinese, I think sticking to that is better. I can create a title like "转会传闻", but it's optional based on guidelines.
My response will include a brief summary with bullet points covering key details:
- 简述
- 明格萨简介/现状
- 50%分成含义解释
- 可能的适配
- 询问用户是否需要跟进来源、最新报价，或者做球探报告/数据对比. 
Keeping it concise is essential!
要点：
- 《阿斯》称：米兰和纽卡想签下奥斯卡·明格萨；巴萨保留50%二次转会分成（sell‑on）。
- 明格萨是拉玛西亚出身的边中卫/右后卫，现效力塞尔塔；若成交，巴萨可分得成交价的一半。
- 适配简评：米兰与纽卡都在右侧/中后卫位置寻求轮换与出球能力，明格萨技术脚下好、可内收组织但对抗与高空一般，偏体系型。
需要我：
- 跟进可靠来源与最新报价区间
- 做一份球探速览（技术特点+数据雷达+适配两队战术）
- 盘点巴萨分成机制对交易结构的影响（含回购/二次转卖风险）
