Providing transfer background
In 2020, a sell-on clause was included for a transfer, and it’s known that €24M was discussed. I’ll mention that the deal reportedly involved a sale percentage, while being careful not to fabricate numbers. I wonder what the user would like next: a summary, more details, or a source link? I'll also provide a brief background about how Milan's management considered an offer for a player but ultimately chose another option due to budget priorities. I'll keep it concise!
确有这样的说法。背景梳理（简要）：
- 2020 夏窗，米兰（马尔蒂尼/马萨拉+球探蒙卡达）深度考察阿尔梅里亚的达尔文·努涅斯，讨论过约2000万欧左右的结构化报价与分期。
- 本菲卡随后出手更快更果断，开出约2400万欧固定费（当时队史纪录）+更优薪资，合同长期，据报道还包含转售分成条款，阿尔梅里亚与球员都更倾向这份方案。 
- 米兰当夏把预算优先用在托纳利、迪亚斯等引援上，努涅斯最终转会本菲卡；2022 年再高价转会利物浦。
需要我找这条消息对应的记者原文/来源链接，还是按时间线把当时的报价细节再展开？
