What is it?
The FedEx Performance Zone tracks players' form for their clubs in their respective domestic leagues as well as in the UEFA Europa League. The Performance Zone runs official player statistics through a specially designed algorithm to create rankings based on player performances.
Player data from domestic matches and qualifying rounds of both the UEFA Champions League (for teams entering via that competition) and UEFA Europa League form the initial basis for the rankings, which have taken into account club performances from 1 July 2016.
This gives a unique and comprehensive evaluation of players' form when the Europa League kicks off, after which the Performance Zone will track which players are excelling in the competition itself.
The FedEx Performance Zone is purely a form tracker and does not suggest that one player is better than another.
How it works
All players are assigned a primary position for which they are expected to play the majority of the time.
The player categories are defined as: goalkeepers, full-backs, central defenders, defensive midfielders, central midfielders, attacking midfielders, wingers and forwards.
The data considered for each player is specific to the position type. For example, tackles and blocks are considered to be key statistics for defensive midfielders, while successful dribbles and crosses are core stats for wingers.
The algorithm uses player stats from matches in each club’s domestic league and updates after these matches are played as well as the UEFA Europa League. During UEFA Europa League match nights, the rankings update live during every match.
As the Performance Zone acts as a form tracker, the more recent the match, the higher the weighting assigned to the data from it, i.e. player stats from yesterday are given more significance than those from last week. If a player is not active (e.g. due to injury or non-selection), his ranking will decrease over that period of inactivity.
Additional weighting is attributed for the domestic competition each team plays in using UEFA coefficients as the foundation of the values.
Once the UEFA Europa League starts, statistical events (e.g. goals, assists, tackles, saves) for all players will be given a significantly higher weighting to maintain an accurate ranking of those performing well in the competition.
