The highest-scored athlete at each post.
Six positions, six leaders. The Index is read by position before it is read by value — a 78-rated CB and a 91-rated RW are not the same kind of asset.
Six dimensions. One number.
Every Index score weights six independent dimensions. The full methodology is open to your committee on request.
Goal probability per possession, shot quality, dribble carries that change phase.
Expected assists, line-breaking passes, chance generation in the attacking third.
Pressures won, recoveries, defensive duels in the player's territorial responsibility.
Sprint distance, high-intensity load, injury exposure modelled against league travel demands.
Performance across formations, positions, opponent style, and competition tier.
Forecast of the next three seasons, weighted on age curve, contract position, and market demand.
Continuously updated. Back-tested against five years of completed transfers. Every Index score is traceable to the data that produced it.
This edition is a demonstration.
