Planning strategy suggestions

This suggests that not "almost no one is available," but rather there are only four players for two positions across competitions, which brings an injury risk.
For strategies, I’m thinking of: 1) buying a long-term starter now; 2) looking for an opportunistic U23 for resale; 3) securing a short-term loan cover; and 4) promoting from the academy and revisiting the situation in the summer.
I’ll also ask how they'd prefer to proceed: deeper scouting, data comparisons, or XI fit. Furthermore, I’ll ensure the answer is prepared concisely in Chinese with bullet points.
简讯解读与建议
这话题的背景:利物浦中卫人数看似有四人,但可持续的“可用性”偏紧。范戴克年龄结构、科纳特伤停史、戈麦斯多面手但非纯中卫、夸恩萨经验尚浅;马蒂普已离队(2024),多线赛程下容错率低,的确容易出现“名额够、可用性却不够”的断层。

我对利物浦的推荐路径
需要我按你心仪的价位和侧重点(左脚/速度/本土)做一份更具体的三人清单和首发/轮换搭配吗?
