About
What this is
PremRefTracker compiles three seasons of Premier League match data and makes it browsable. Cards, penalties, and fouls, split by referee, team, and venue. The data is public. The patterns are there. We just put them in one place.
This is independent fan analysis. We're not affiliated with PGMOL, the Premier League, or any club. We have no commercial interest in any outcome. The goal is transparency. Nothing more, nothing less.
Data sources
- football-data.co.uk: match results, yellow cards, red cards, and fouls for all Premier League games from 2023/24 through the current season. Free, publicly available.
- FBref / Sports Reference: per-match penalty attempts (PKatt) and possession figures, used to normalize penalty analysis by attacking intent. Publicly available.
- API-Football: event-level data (card timing, VAR decisions) for deeper drill-down. Used to build the event cache underlying card timing and VAR statistics.
Methodology
A−H Diff: Away minus Home yellow cards per game, for a given referee. A positive number means that referee books away teams more heavily than home teams, relative to their own average. The league-wide average is positive (away teams receive more bookings), so this metric shows deviation from the norm.
Penalty Bias: the share of a referee's penalties awarded to the home team, minus the expected share based on average home possession across their matches. Possession is used as a proxy for attacking intent: a team with 60% of the ball should, in theory, generate proportionally more penalty-worthy situations. A positive bias score means home teams received more penalties than possession alone would predict.
All statistics cover Seasons 2023/24, 2024/25, and 2025/26. Sample sizes vary; referees with fewer games or fewer penalties are flagged where relevant. Small samples can produce extreme numbers, so interpret accordingly.
