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 Tiago Martins turns into bookings. Conversion, not the raw foul count, is where a referee's real card tendency lives. Career figures across every Primeira Liga season on record.

Frequently asked
How many cards does Tiago Martins give per game?
Tiago Martins averages 5.83 cards a game across 30 Primeira Liga matches — 13% above the league average of 5.17. On a Tiago Martins appointment, the model multiplies every player's booking chance by 1.13.
Is Tiago Martins a strict referee?
Yes. The honest measure is foul-to-card conversion — the share of fouls that become bookings — and Tiago Martins runs at 25.0% 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 Tiago Martins'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 Tiago Martins's card rate?
It rests on 30 career matches, a solid record. 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.
