Roles and similarity

Generated 2026-10-15T15:37:54+00:00. Per-90 FPL/Opta profiles, players with >= 900 minutes in a season. Features: xg, xa, goals, assists, threat, creativity, influence; plus tackles, recoveries, cbi from 2025-26 (when FPL started tracking them).

Similarity: does a player's profile find his own previous season?

Seasons Players Top-1 Top-5
2022-23 -> 2023-24 116 9.5% 38.8%
2023-24 -> 2024-25 148 13.5% 38.5%
2024-25 -> 2025-26 171 9.9% 36.3%
random guess 3.4% 17.1%

Roles (2025-26)

Limitation: FPL/Opta box-score profiles cannot see positioning or passing networks; event or tracking data would separate roles more finely. Player embeddings (FootballBERT) are pending a decision on loading third-party weights.
