What Is The Squawka Performance Score?

The Performance Score is a measure of a player’s ability to positively influence a game of football. The more positive influence you have on the ball, the higher your Performance Score. The more negative influence, the lower your performance score. The Performance Score is an advanced algorithm that takes every recorded on-ball action on the football pitch, evaluates its outcome, pitch co-ordinates, playing position of the player and the preceding event.

So how does it work?

In simple terms, the algorithm takes each on-pitch action, processes it and allocates it a score. The performance score simply adds all these scores together. The Performance Score is broken down into 3 components; attack, defence and possession. The attack aspect takes all the attacking events into consideration (shots, crosses, take-ons, etc…) The defence aspect scores defensive actions (e.g tackles, interceptions, etc.) The possession component scores passes, through-balls, etc… The algorithm scores each event independently. Each on-ball action has a base score, this score is then multiplied by an Execution Qualifier, Outcome Qualifier, Player Qualifier and Area Qualifier.

Actions: 28 types

Including passes, shots, saves, take-ons, clearances, fouls, tackles, cards, interceptions, blocks, key passes etc.

The overall outcome is an algorithm calculated using over 500,000,000 data points

Players who have had an average game over 90 minutes can expect a score of between 10 and 20 points. A minus score indicates a poor game and a score over 50 shows the player is performing well. Unlike most rating systems, which give scores out of 10, there is no limit to how many points a player can score (positively or negatively) on the Squawka Player Performance ratings system. They are as good, or as bad as their involvement, influence and skill allows.

Where do we get our Data from?

We get our data from the Premier League’s official data provider Opta. We receive feeds that are delivered to Squawka live in-game. We then process these feeds and extract the data. This data is then fed into the Performance Score Algorithm and processed in our live match centres in real-time.
