The CONMEBOL Copa America (CONMEBOL America Cup), formerly known as the South American Football Championship (Campeonato Sudamericano de Futbol in Spanish and Copa Sul-Americana de Futebol in Portuguese) until 1975, is the premier men's football competition contested by CONMEBOL national teams. A team wins a cup title if they win both the first leg of the final match and also the second leg/match after extra time have been played. If there are still ties after that stage then the penalty shoot-out will be used to determine who wins. The CONCACAF Gold Cup is the most prestigious international tournament in North and Central America hosted by the United States since 1991. It is an annual event which pits the winners of each National Team Association against one another to compete for the Gold Cup. The tournament consists of three stages: a group stage, followed by a knockout stage. The group stage sees the eight teams being divided into two groups of four. Each group plays on a round-robin basis with each team playing the others once at their home stadium. The top two teams from each group advance to the quarterfinals. The third-place finisher from each group meets the fourth-place finisher from another group to determine which nations qualify for the semi-finals. The winner of this stage is determined by points obtained during the group stage.
