FedEx Performance Zone: how it works
Who are the form players at UEFA EURO 2020? Using a specially devised algorithm, the FedEx Performance Zone reveals all.
What is it?
The FedEx Performance Zone is tracking players' form for their countries at UEFA EURO 2020. Data from the UEFA Nations League, European Qualifiers and international friendlies was fed into a specially designed algorithm to create pre-tournament rankings based on performances. Updates every matchday at EURO 2020 factor in players' subsequent displays at the final tournament.
The FedEx Performance Zone purely charts the form of players for their national teams and does not suggest that one player is better than another.
How it works
Every player is assigned a primary on-field position, where they are expected to play the majority of the time. The categories are goalkeepers, defenders, midfielders and forwards.
The data considered for each player is specific to their position. For example, clean sheets, tackles and recovered balls are considered key statistics for defensive players, while goals, assists, crosses and passes are important metrics for midfielders and forwards.
The algorithm uses player stats to deliver updates after games are played, with the rankings updating live as the games unfold.
Since the FedEx Performance Zone acts as a form tracker within national-team competitions, no consideration is given to players' showings for domestic clubs.
Performances in the UEFA EURO 2020 group stage are weighted equally, although matches in subsequent rounds of either competition are weighted incrementally higher. International friendlies carry a lower weighting than competitive matches.
The quality of opposition is factored into the algorithm too, with nations weighted according to UEFA's country coefficients.
