Qualification berths for the Olympic Games are allocated to each continent. In men’s football, sixteen qualified teams are allocated to four groups (A, B, C, and D), and play group stage matches. The top two teams of each group advance to the quarterfinal stage.
In women’s football, twelve qualified teams are allocated to three groups (E, F, and G), and play group stage matches. The top two teams as well as the best two teams from the top three teams of each group advance to the quarterfinal stage.
Mens’ and women’s teams play a knockout tournament in the quarterfinal. If a match is drawn after 90 minutes, the teams will play extra time (two periods of 15 minutes each). If the scores are level at the end of extra time, the two teams take part in a penalty shoot-out to determine which team progresses to the next round. As for the third-place match, the teams will take part in a penalty shoot-out, but not playing extra time, to determine the winner, if the match takes place at the same day at the same stadium with the final stage.
