Considering price suggestions
I want to be factual and avoid giving definite numbers that might be incorrect. A suggestion like "≤£45m" could seem too specific. Instead, I think I should generalize and say something like "若费用在中等区间而非顶薪顶价" (if the cost is in the mid-range rather than at the top salary level). Some estimates are fine, but I want to present them as opinions while steering clear of hard contract details.
如果按“立刻提升即战力”的思路，大马丁确实能帮切尔西：
- 门线与制空强、定位球与点球能力顶级，性格强硬，关键战稳定性高
- 更衣室话事力与经验，对年轻阵容是加成
但也有清晰的隐忧：
- 年龄与薪资结构：转会费+高工资会占用PSR/FFP空间，机会成本大
- 适配度：若强调控球与从后场组织（马雷斯卡式），他脚下传控只是合格并非顶级 
- 阵容权衡：佩特罗维奇成长迅速，用高薪老将堵上路需要非常确定的“马上出成绩”诉求
- 交易难度：维拉不易放人，价格和谈判强度都高
结论：如果切尔西目标是短期冲击冠军、且价格与薪资在可控区间，这笔引援有逻辑；若侧重长期资产与风格统一，继续押注佩特罗维奇或寻找更年轻、脚下更强的门将更稳妥。
需要我：
- 写一段新闻简讯/标题文案，还是
- 做一版更详细的转会可行性评估（费用带、薪资结构、风格匹配与替代名单）？
