The XI was picked from the top players in each position, though in midfield the second-best defensive midfielder Eric Dier (9th overall) was chosen ahead of the top winger Antonio Candreva (17th). Sergio Ramos (8th) and Luka Modrić (10th) are the only top ten players to miss out, thus allowing the selection of a goalkeeper and two full-backs.

The XI before matchday one: Neuer (GER); Juanfran (ESP), Koscielny (FRA), Ramos (ESP), Bellerin (ESP); Soriano (ESP), Milner (ENG); Griezmann (FRA), Payet (FRA); Ronaldo (POR), Ibrahimović (SWE).

How it works

The UEFA EURO 2016 Player Barometer is tracking players' form during the tournament. The Barometer runs official player statistics through a specially-designed algorithm to create rankings based on player performances.

Player data from qualifying formed the initial basis for the rankings, which have taken into account performances for club and country since 1 January 2016. This gave a unique and comprehensive evaluation of players' form when UEFA EURO 2016 kicked off, after which the Barometer tracks which players are excelling in the tournament itself.

As the Barometer acts as a form tracker, the more recent the match, the higher the weighting assigned to the data given i.e. player stats from yesterday are afforded 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.
