The tournament organizers established a requirement that all matches had to have a winner and had chosen an odd form of the golden goal rule, which meant that the first goal scored in extra-time not only won the match, but also counted as a double. This differed from most other forms of the rule in that if the winning team already had enough goals to win the match before the end of extra-time they would advance instead of having their victory denied. If the first goal is scored during extra-time then the game continues until one side can claim a victory by scoring a second goal. This means that if the score is level after 120 minutes have been played there will be a winner and a loser despite the fact that no actual winners or losers are determined until after these games have gone to penalty shots. The golden goal rule has been used in several other international tournaments including the Confederations Cup (2005), the King's Cup (2006) and the Arab Cup (2007). Its use is now limited to minor domestic competitions such as the Football League Trophy and FA Trophy. Its introduction into major international tournaments caused problems for those competing. For example, Guadeloupe failed in its attempt to qualify for France 1998 using this method while Trinidad and Tobago was disqualified from Mexico 1990 because it had more than half of its goals in extra-time. However, both countries succeeded in qualifying using this method at the subsequent tournaments.
