What this tool compares
Pick two players from the leagues we cover and the comparator puts them side by side on the same scale: output (goals, assists, shots, conversion), involvement (minutes, appearances, starts), on-ball work (passes, key passes, accuracy, dribbles) and off-ball work (tackles, interceptions, duels won). Goalkeepers swap that panel for saves, goals conceded and save percentage.
The bars are not measured against an invented maximum: each value is compared with players in the same position in our 2026/27 dataset. That is why a full-back with 3 goals can score higher than a striker with 8 — what is measured is how far someone stands out within their role.
Where the data comes from
Stats come from API-Football and are regenerated twice a week into a static file: opening this page queries no API, so it loads fast and returns the same thing for everyone. A player shows up in the comparator once they have recorded minutes this season; if they moved to another league or have not debuted yet, their profile still exists and says so.
How to read the IIG
The IIG (Goal Impact Index) condenses attacking contribution per minute played into one number: it weighs goals and assists against time on the pitch, so a substitute who decides matches is not buried under a starter who plays every minute. It is useful for comparing two players with very different minutes; it is not meant as an overall rating of a footballer.
Honest limits
Comparing numbers across leagues is tricky: 10 goals in the Premier League and 10 in the Eerste Divisie are not the same, and the comparator applies no strength-of-league adjustment. It also does not measure tactical context, team quality or the opponents faced. Use it to see differences in profile and output, not as a verdict on who is better.
