In 1979, the Yugoslav League had a score of 134 to 1.

Two teams from the African island nation of Madagascar set a terrifying record of 149 to 0 in the sixth round of the domestic championship on 31 October 2003.

The winning side was called AS Ademar, but none of the 149 goals came from the feet of the AS Ademar players, and all of them came from the losing side, Olympic Emine. In other words, the losing side contributes 149 own goals to the opponent.

The history-making process went like this: Olympic Emine's head coach Ratsmandrese Ratsarazaka got into an argument with the referee on duty during the match, and as a result, Olympic Emine's players frantically attacked their own gate in order to vent their anger. Whenever he kicked off from the middle circle, the players of the whole team shot at their own goal in unison, scoring one goal after another to make the opposing players stand still, and the referee did not stop the game, and finally 149-0 - the first disparity score in the history of world football was born.

The record for the highest score officially recognized by FIFA came on 12 September 1885 in the Scottish FA Cup match between Abroshe and Bonn Akkard, where the former beat the latter by a stunning score of 36:0.

The biggest disparity in World Cup qualifying came on 11 April 2001, when Australia beat Samoah 31-0. FIFA confirmed the record the following day.

Towards the end of the second half of the game, the scoreboard operator gave Australia an extra goal to make the score 32-0, but FIFA audited and confirmed the final score to be 31-0.

However, not only is American Samoa ranked last in the FIFA rankings, but the vast majority of the country's players did not qualify because they did not have US passports, and the average age of the national team members who played was only 19 years old, with the youngest being only 15 years old!
