Career profile
The two numbers that matter are vs league — the multiplier the model applies to a player's booking chance — and conversion, the share of fouls Donald Robertson turns into bookings. Conversion, not the raw foul count, is where a referee's real card tendency lives. Career figures across every UEFA Conference League season on record.

Frequently asked
How many cards does Donald Robertson give per game?
Donald Robertson averages 3.00 cards a game across 3 UEFA Conference League matches — 33% below the league average of 4.49. That's a raw rate from only 3 matches, so the model shrinks it toward the league average rather than trusting it outright.
Is Donald Robertson a strict referee?
No — more lenient than most. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Donald Robertson runs at 14.8% against a league average of 19.0%. Foul counts barely vary between officials; the rate at which a foul becomes a booking is where referees genuinely differ.
Does Donald Robertson's record change bet builder card prices?
It should. The referee is the single biggest factor in the to-be-carded market, and the appointment is public before kick-off — so a strict official on a combative player is the archetypal card edge. The player cards guide walks through exactly how the model turns a tendency like this into a price.
How reliable is Donald Robertson's card rate?
It rests on 3 career matches, still a thin sample — read it gently. The model shrinks a referee's tendency toward the league average when the sample is thin and discounts its own confidence for officials with young records, so a number like this never gets trusted beyond what the evidence earns.
Rates shown are figures from public match data for context; the model adds shrinkage and an opponent factor, and discounts its confidence for thin referee records, before flagging any card as value. It compares against the bookmaker's price as offered — card markets are priced one side only, so that price still carries the bookmaker's margin. 18+ — please gamble responsibly.
