In 1984,1988 and 2000, Nigeria reached the Cup of Nations final, losing to Cameroon. Three of the five African titles won by Cameroon have been won by defeating Nigeria. Missing out to Cameroon on many occasions has created an intense rivalry between both nations. Three notable occasions; narrowly losing out in the 1988 African Cup of Nations, qualifiers for the 1990 World Cup, and then the controversial final of the 2000 African Cup of Nations where a kick taken by Victor Ikpeba during the penalty shoot-out was adjudged not to have crossed the goal-line by the referee.
