Methodology
Club assessment — the universe of signings
The report considers exclusively genuine signings for the first-team squad, identified by the player's effective incorporation into the group between seasons. Excluded from the universe are: academy promotions, loan returns, internal administrative moves and transfers recorded but never completed. The aim is to measure the quality of market decisions — and those alone.
Player Impact Score (PIS)
Each evaluated signing receives a score from 0 to 100 that combines four observable technical dimensions: individual performance (average match ratings over the season), output (goals, assists and decisive actions adjusted for game time), collective performance (starting status and correlation with the club's results) and availability (volume of matches, adjusted for interruptions). High-impact players with reduced game time are promoted through an alternative efficiency criterion.
Outcome classification
The rating tiers are: Excellent and Good (successful signings — a full point in the index), Fair (intermediate performance — half a point) and Below expectations / Did not deliver (unsuccessful signings). Two categories sit outside the calculation, for distinct reasons: Injury (a serious injury prevented a fair assessment) and Investment (an under-23 player with low game time — the return depends on development and cannot be counted for or against the club in this cycle). Signings that did not reach relevant game time in the season are classified as unsuccessful, reflecting the sporting cost of the decision.
A note on scope
This is SigningLab's public, simplified model, developed for transparent retrospective market assessment. SigningLab's commercial solutions for partner clubs use a substantially larger set of variables and dedicated predictive mechanisms, and are not fully reflected in this document.
