Open any live score app after a match and you will see a number next to every player: 6.4, 7.8, 9.1. These player ratings have become part of how fans judge performances, but few people know what goes into them. This guide explains how ratings work on the major platforms, what they are good for, and where they can mislead you.

Most ratings come from data providers that feed apps like Sofascore, FotMob and WhoScored. Each player starts a match around 6.0 or 6.5, and the rating moves up or down based on hundreds of recorded events: passes, tackles, shots, dribbles, duels won and lost, and mistakes. A goal or an assist gives a big boost, while a red card or an error leading to a goal drags the number down sharply.

Sofascore Ratings Explained

Sofascore has rated players since 2015, using an algorithm that processes hundreds of data points per match. On a top-league game, Sofascore shows xG, shots, a momentum graph and a rating for every player. Click on a player and you get a breakdown of their actions plus a pass map.

The strength of Sofascore is consistency: the same formula applies to every player in every match, so ratings are comparable across leagues and seasons. The weakness is that the exact formula is not published, so you cannot know precisely how much a tackle is worth versus a key pass. Treat the number as a useful summary, not a scientific verdict.

FotMob and WhoScored: Different Recipes

FotMob also provides algorithmic ratings on a 0 to 10 scale, with a focus on clear, visual presentation of the underlying stats. WhoScored, built on Opta data, is known for its detailed statistical ratings and its habit of rewarding players who are heavily involved: a midfielder who completes 90 passes and wins 10 duels will score highly even without a goal or assist.

The practical point is that the same performance can earn different ratings on different platforms. A defender who makes 12 clearances and wins every header might score 8.0 on WhoScored but only 7.2 on Sofascore, because the two systems weigh defensive actions differently. If you compare players, use one platform consistently.

What Ratings Get Wrong

Ratings are event-based, which means they reward what can be counted and undervalue what cannot. A striker who makes a clever run that drags two defenders away gets nothing for it. A midfielder who controls the tempo with simple, safe passes may score lower than one who attempts risky through balls all game. Leadership, positioning and off-the-ball movement are almost invisible to the algorithm.

Ratings also struggle with context. A 7.5 against the league champions is a better performance than a 7.5 against a relegation side, but the number does not tell you that. And a player who comes on as a substitute for ten minutes may be excluded from the average entirely if there are too few events to score fairly.

How to Use Ratings Properly

Use ratings as a starting point, not a conclusion. Check the rating, then look at the underlying numbers: pass accuracy, duels won, chances created, shots on target. A high rating backed by strong underlying stats is meaningful. A high rating built on a single goal, with poor numbers elsewhere, tells you the player had one good moment, not a good game.

For fantasy football and betting, ratings are genuinely useful. Players who consistently score above 7.0 are usually involved in everything their team does well. But always pair the number with your own eyes: watch the match, or at least the highlights, before you decide a player was brilliant or terrible based on a decimal.
