Player Intelligence
Experimental in-house signals derived from completed fixtures only. They describe what the data shows — they are not official ratings, and they are not predictions.
Efficiency Index
Highly efficient
Useful output divided by relevant attempted actions, weighted for the player's role.
Opposition Index
Balanced schedule
Minutes-weighted strength of the opponents actually faced. Context only — it does not adjust the Impact Score.
Momentum Index
Steady form
Last 2 scored matches 52.8 vs earlier 51.1 (+1.6).
Breakout Index
No clear movement
Signal, not a prediction: recent impact, minutes and starting involvement, read against role-relative standing and opponent strength.
Decline Index
No clear movement
The same development axis read downwards. A signal of sustained negative movement, not a prediction.
Final-third profile
Per-90 attacking output from fields the provider actually records. Expected goals, expected assists and spatial metrics are not available in this data and are not estimated.
| Metric | Per 90 |
|---|---|
| Passes in final third per 90 | 3.55 |
| Key passes per 90 | 0.82 |
| Chances created per 90 | 0.82 |

| Crosses per 90 | 1.36 |
| Shots per 90 | 1.27 |
| Successful dribbles per 90 | 0.36 |
Team effect
Observational, not causal: team points per completed fixture with and without this player in the starting eleven.
Difference: +0.08 points per match. This is a description of results only and does not establish that the player caused them.

Goals, assists and yellow cards are counted from recorded match events, so a 0 means the event did not occur. A dash means the provider sent no value — it never means zero. Match impact is only shown for appearances of at least 30 minutes with sufficient metric coverage.

Methodology
Data source
Match, lineup, event and player statistics come from Sportmonks and are stored per fixture. Only completed fixtures with recorded minutes are aggregated — announced lineups and future fixtures are excluded.
Per 90 minutes
A per-90 value scales a season total to a full match: total × 90 ÷ minutes played. It is not calculated when minutes are missing or zero.
Missing data
The provider omits some statistics instead of sending a zero. A missing value is shown as "not available" and never converted to 0, so rates and percentiles are only produced where the underlying fields genuinely exist.
Impact Score
The Football Performance Lab Impact Score is an experimental in-house model that combines role-relative percentile families with explicit weights. It is not an official rating and not a measure of transfer value.
Minimum samples
Values are calculated internally from 180 minutes, but a player is only shown publicly with a ranked Impact Score from 360 minutes and 5 appearances, with at least 90% metric coverage and an established role. A single appearance contributes a match impact observation from 30 minutes.
