The UEFA European Under-17 Championship consists of three distinct stages: the qualifying round, the elite round and the final tournament. The format changed for 2014/15 with the expansion of the final tournament from eight to 16 teams.
The qualifying round, played in autumn, is made up of 13 groups of four countries playing in one-venue mini-tournaments. The top two from each pool progress alongside the four third-placed sides with the best record against the leading pair in their groups.
In the elite round, held in early spring, those 30 qualifiers plus the top two seeds – given a bye this far – compete in eight mini-tournament groups of four. The group winners and seven runners-up with the best record against the teams first and third in their section advance to the finals to join the hosts.
In the final tournament the contenders are split into four groups of four, with the front two from each proceeding to the knockout phase.
Further details, including the criteria for separating sides that finish level on points in a group, or after 80 minutes in a match, can be found in the official competition regulations.
The No9 shot France in front in their Group B opener versus Hungary. His late second, an added-time penalty, was mere consolation as Lionel Rouxel's side started their campaign with a 3-2 reverse.
Gouiri and his team-mates flew out of the traps three days later against UEFA finals debutants the Faroe Islands. France were 5-0 to the good by half-time thanks largely to a 33-minute hat-trick by the Lyon forward. Les Bleus went on to post a U17 EURO finals record 7-0 victory.
The 17-year-old then spared his team from elimination in dramatic style. Needing to defeat Scotland in their last group fixture to progress, France were drawing 1-1 going into the last minute. Up popped Gouiri at the far post, taking down a cross from Yacine Adli and dispatching his second of the game past Scotland keeper Jon McCracken.
Gouiri and Spain captain Abel Ruiz went into their quarter-final on Friday level on seven U17 EURO finals goals, Ruiz having scored four in Azerbaijan 12 months ago and three times in Group A here in Croatia.
Gouiri forged ahead early on, equalling the record held by compatriot Odsonne Edouard, and was soon joined on eight goals by Ruiz when the Barcelona player converted a penalty to put La Roja 2-1 up. France eventually lost 3-1.
