The golden goal and the silver goal: the rules that no longer exist

Between 1998 and 2002, a goal in extra time could end the match instantly. Laurent Blanc scored the first in World Cup history; İlhan Mansız the last.
For a few years, football experimented with a rule as thrilling as it was cruel: the «golden goal». Introduced by FIFA in the 1990s, it established sudden death in extra time: the first team to score won and the match ended at once.
The first golden goal in World Cup history was scored by France's Laurent Blanc, on 28 June 1998, in the 114th minute of the round of 16 against Paraguay. France went on and were eventually crowned world champions at home.
The last came in 2002: Turkey's İlhan Mansız scored in the 94th minute of the quarter-final against Senegal, and Turkey reached the semi-finals on the way to a historic third place.
There was also a shorter variant, the «silver goal» (2002-2004): if a team was ahead at the end of the first 15-minute period of extra time, it won, without waiting for the second. Neither rule fully convinced.
In February 2004, the IFAB abolished both and football returned to the full 30-minute extra time. The golden goal passed into history as a fleeting, unforgettable experiment.
