A metric that can quantify the extent and aggression of high presses employed by teams, both over a season and in any specific match.
The goal is define the intensity of a press with the use of numbers, more specifically by using some specific events.
and reduce it to one number so that it allows for comparison, analysis and ranking.
To measure the pressure that the defending team puts on the opposition players when they are in possession of the ball.
The definition of PPDA is:
PPDA = Number of Passes made by Attacking Team (oppoenent) / Number of Defensive Actions
The PPDA metric is calculated by dividing the number of passes allowed by the defending team by the total number of defensive actions.
Where Defensive Actions are:
possession-winning duels, tackles, interceptions, fouls
Both values (passes made and defensive actions) will be calculated in opponent’s final 60% of the pitch.
