We are in the knockout round of Euro 2021 and if the latest editions of the tournament are any indication, we will have a share of matches that will remain deadlocked after 90 minutes.
The official tournament rules for the European Championship (page 20) describe what happens after 90 minutes of settlement if the score is still tied:
- Extra time: Two 15-minute overtime periods played in their entirety;
- Penalty kicks: If there is still no winner after extra time, a penalty shootout will be used to determine a winner.
Substitutes in overtime
Each team is entitled to five substitutions in each game of the competition and an additional sixth substitute may be used exclusively during extra time.
These substitutions must take place for a maximum of three in-game substitution windows if the game ends in regular time or four in-game substitution windows if the game goes into overtime.
Teams can also make substitutions at the end of different periods that will not count towards in-game replacement windows:
- half-time settlement
- end of settlement
- half of extra time
What happened in 2016
In the last edition of the European Championships, five of the 15 matches in the knockout stage required extra time and three of those five matches resulted in penalties.
The Euro 2016 final between Portugal and France was decided by an overtime goal in the 109th minute by the Portuguese Eder.
Poland (round of 16), Portugal (quarter-final) and Germany (quarter-final) were the teams that won the penalties in the round of 16 of this tournament against Switzerland, Poland and the ‘Italy, respectively.
Six of the 15 all-time European Championship finals were played in overtime with only one penalty shootout ending: Czechoslovakia won the crown against West Germany in 1976.
The Euro 1996 and 2000 finals were decided by a sudden death “golden goal” in overtime. At the time, the rules determined that the first goal scored in overtime was the match winner, thus ending the match. The golden goal rule has since been repealed.
