The 2019 UEFA European Under-21 Championship (also known as UEFA Under-21 Euro 2019) is the 22nd edition of the UEFA European Under-21 Championship (25th edition if the Under-23 era is also included), the biennial international youth football championship organised by UEFA for the men's under-21 national teams of Europe. The final tournament is hosted by Italy (and some matches by San Marino) in mid-2019, after their bid was selected by the UEFA Executive Committee on 9 December 2016 in Nyon, Switzerland.
A total of 12 teams will play in the tournament, with players born on or after 1 January 1996 eligible to participate.
Same as previous Under-21 Championships that were held one year prior to the Olympics, this tournament will serve as European qualifying for the Olympic football tournament, with the top four teams of the tournament qualifying for the 2020 Summer Olympic men's football tournament in Japan, where they will be represented by their under-23 national teams with maximum of three overage players allowed. The four teams that will be qualified for the Olympic Games are the ones that wil be qualified for the knockout stages of this championship. For the first time, the video assistant referee (VAR) system will be used at the UEFA European Under-21 Championship.
All 55 UEFA nations entered the competition, and with the hosts Italy qualifying automatically (the other co-hosts San Marino would not qualify automatically), the other 54 teams competed in the qualifying competition to determine the remaining 11 spots in the final tournament. The qualifying competition, which took place from March 2017 to November 2018, consisted of two rounds:
Qualifying group stage: The 54 teams were drawn into nine groups of six teams. Each group was played in home-and-away round-robin format. The nine group winners qualified directly for the final tournament, while the four best runners-up (not counting results against the sixth-placed team) advanced to the play-offs.
Play-offs: The four teams were drawn into two ties to play home-and-away two-legged matches to determine the last two qualified teams.
The 12 teams were drawn into three groups of four teams. The hosts Italy were assigned to position A1 in the draw, while the other teams were seeded according to their coefficient ranking following the end of the qualifying stage, calculated based on the following:
Each group contained either the hosts or one team from Pot 1 (which were drawn to position B1 or C1), and one team from Pot 2 and two teams from Pot 3 (which were drawn to any of the positions 2–4 in the groups). The draw pots were as follows:
Each national team have to submit a squad of 23 players, three of whom must be goalkeepers, at least 10 full days before the opening match. If a player is injured or ill severely enough to prevent his participation in the tournament before his team's first match, he can be replaced by another player.
The group winners and the best runners-up advanced to the semi-finals and qualified for the 2020 Summer Olympics.
In the group stage, teams were ranked according to points (3 points for a win, 1 point for a draw, 0 points for a loss), and if tied on points, the following tiebreaking criteria would be applied, in the order given, to determine the rankings (Regulations Articles 18.01 and 18.02):
Goals scored in head-to-head matches among tied teams;
If more than two teams are tied, and after applying all head-to-head criteria above, a subset of teams are still tied, all head-to-head criteria above would be reapplied exclusively to this subset of teams;
Goal difference in all group matches;
Goals scored in all group matches;
Penalty shoot-out if only two teams have the same number of points, and they met in the last round of the group and are tied after applying all criteria above (not used if more than two teams have the same number of points, or if their rankings are not relevant for qualification for the next stage);
Disciplinary points (red card = 3 points, yellow card = 1 point, expulsion for two yellow cards in one match = 3 points);
Position in the UEFA under-21 national team coefficient ranking for the final draw.
England were ineligible for the Olympics as they are not an Olympic nation. Had they reached the semi-finals, the last Olympic spot would have gone to the winner of an Olympic play-off match scheduled to be played on 27 June 2019 at Stadio Dino Manuzzi, Cesena between the two group runners-up which did not qualify for the semi-finals. However, when England failed to advance out of the group stage, this match was cancelled.
