想做哪种统计？先帮我确认这些关键信息：

• 联赛与赛季范围（例如 2024-25 英超，或最近3赛季）
• 数据来源（你有现成CSV/Excel吗？还是让我抓 FBref/Understat/StatsBomb 开源数据）
• 指标口味与输出形式（榜单/表格/雷达图；导出 CSV/Excel/图片；是否分位置）
• 最低上场门槛（如 ≥900 分钟）与是否做每90分钟标准化与百分位

建议统计维度（按位置分层并做每90 + 百分位）：

• 进攻产出：非点球进球、助攻、npxG、xA、射门、关键传球、SCA/GCA
• 推进威胁：推进传球/带球、进攻三区传球、进禁区传球
• 终结效率：进球 - xG、每射门进球、射正率
• 组织与连接：传球尝试/成功率、三分之一/禁区传球成功率
• 防守与对抗：抢断、拦截、压迫、空中对抗胜率、地面对抗
• 可用性：出场分钟、首发次数、位置标签（FW/MF/DF，或更细分）
• 综合：按权重或PCA构建“关键球员评分”，并输出榜单

下面给你一个可直接跑的 Python/pandas 脚本雏形：读取一个球员赛季汇总 CSV，计算 per90、百分位与综合评分，并导出榜单。你只需把列名映射到你实际数据即可。

使用方法

• 准备一个 players.csv，至少含这些列：player, team, pos, minutes, goals, assists, shots, key_passes, xG, xA；其余列缺失也可运行。
• 若你的列名不同，把脚本顶部 EXPECTED 右侧的值改成你实际列名。
• 运行：python key_players.py，会生成 leaders.csv（联赛榜单）与 by_team_top.csv（各队内Top5）。

需要我：

1. 直接对接你已有CSV做一次适配与输出图表；
2. 帮你抓取指定联赛赛季的数据并清洗成上述格式；
3. 调整权重/指标，做专属“关键球员评分”和雷达图。

给我一个样例数据头几行或说明目标联赛与赛季，我就继续完善到可复用的管道。
