On 27 January 1994, Barbados and Grenada clashed in a qualification match for the 1994 Carribean Cup.
Due to an unusual rule and also due to the group standing, Barbados needed to win by a margin of two goals or more to qualify while a draw would take the game into extra time.
Also, according to the rule, which was a variant of the Golden Goal rule, a goal scored in extra time not only won the match, but also counted as two goals.
By the 83rd minute, Barbados were leading 2-0 and had hopes of qualifying. But Grenada scored a late goal to make it 2-1 and Barbados had limited time to score and restore their two-goal advantage.
So they decided to score an own goal and force the match into extra time, where they hoped to score a golden goal, which would count as two goals and restore their two-goal advantage.
With the scoreline at 2-2, Grenada just needed to score in either goal to qualify (since a 1-goal win margin would knock Barbados out).
The Barbadians realizing what was going on, had to defend both goals- and they succeeded in doing so. The game progressed to extra time and Barbados scored a golden goal which ensured their qualification.
The Grenadian manager James Clarkson did not find it funny, saying;
"I feel cheated. The person who came up with these rules must be a candidate for a madhouse.
"The game should never be played with so many players running around the field confused. Our players did not even know which direction to attack: our goal or their goal. I have never seen this happen before. In football, you are supposed to score against the opponents to win, not for them."
