As explained in this article, the Performance metrics in the SciSports Platform assess the impact of each player's actions on the course of a match.
The defensive variant of Performance considers the actions that mostly contribute to preventing goals. We measure a player’s Performance on a range of four distinct action types. This includes Prevention, Recoveries, Pressing and Defensive Positioning. The overall chart shows the total contribution on all four action groups. All the defensive performances are compared to players in the same position and league, normalised to a per 90 minutes basis.
Below, Sergio Ramos' defensive metrics are shown compared to other La Liga centre backs in the selected season. By navigating through each action group, users will then see a breakdown of how Ramos ranks in specific action types.
As you will see below, we have included some video examples of specific action types.
