Considering roster adjustments
I'm thinking about the roster size and budget constraints. It seems they need to offload a forward like Jovic before they can bring someone new in. There's a mention of 'Santiago' as a possible player involved, but I'm not sure if that's someone in the squad or loaned out. I should confirm who that is to get a clear picture. Let's figure this out!
这是条新闻标题吧？大意：如果“圣地亚哥”不离队，AC米兰冬窗就无法引进新中锋。
需要我做什么吗？
- 翻译成英文或改写
- 查源/核实出处 
- 解释背后原因（名单名额、薪资空间、非欧名额等可能约束）
- 盘点米兰可能的前锋引援与清洗方案
- 快速点评这条传闻的可信度
另外，“圣地亚哥”指的是哪位球员？目前米兰一线队并没有直接叫 Santiago 的常用注册名，可能是中文媒体的昵称或青训小将的译名，确认下我再给你更精确的分析。
