Football is a great game, one we all love or wouldn't be here. But sometimes it degenerates into a farce due to competition rule makers not thinking things through well enough. My first contribution to this thread goes back to 1994 and the Caribbean Cup tournament of that year, more precisely the last group game in Group 1, Barbados v Greneda. Grenada went into the match with a +1 goal difference advantage over Barbados meaning Barbados had to beat Grenada by two goals to win the group and progress to the next stage, with me so far?
The farce that was to follow was caused by the fact that the organisers had decided that every game must have a winner; any game tied after 90 minutes would go to a 'golden goal' extra time and, crucially (and daftly) that the golden goal would count double!
Barbados seemed to have everything in their hands leading 2-0, a score that would have seen them qualify on goal difference. Then, in the 83rd minute Grenada pulled one back meaning at 2-1 Barbados now needed another to qualify. The Barbadians realised they had little if any chance of scoring past the massed Grenada defence and in a moment of genius decided that their best bet was to take the game to extra time in the hope of scoring the golden goal which would count double and given them their two goal margin. So they scored an own goal making it 2-2.
But the farce wasn't over because Grenada realised themselves that if they could score at the right end the game would finish 3-2 to them and they would qualify with more points. They also realised that they could also score an own goal giving Barbados the win by just one goal, a result that would see Grenada qualify on goal difference; either way they qualified. The game ended with the ridiculous sight of Barbados defending both goals to thwart the Grenadians plan and they managed to hold off until extra time when they did in fact score the crucial double golden goal and qualified 4-2.
