The 1986 FIFA World Cup, the 13th FIFA World Cup, was a quadrennial football tournament for men's senior national teams, was held in Mexico from 31 May to 29 June 1986. The tournament was the second to feature a 24-team format. With European nations not allowed to host after the previous World Cup in Spain, Colombia had been originally chosen to host the competition by FIFA but, largely due to economic reasons, was not able to do so and officially resigned in 1982. Mexico was selected as the new host in May 1983, thus becoming the first country to host the World Cup more than once.
It was won by Argentina (their second title, after winning in 1978). Argentina was captained by the 25-year old Diego Maradona, who played a large part in his team's success by scoring the "Hand of God" goal, as well as another voted "Goal of the Century", in the same quarter-final against England. These were two of the five goals that Maradona scored during the tournament, and he also created another five for his teammates. Argentina beat West Germany 3–2 in the final at Mexico City's Estadio Azteca. Total attendance was 2,394,031, an average per match of 46,039. Canada, Denmark and Iraq made their first appearances at the final stage.
The format of the competition changed from 1982. The final pair of matches in each group started at the same time and the second round was played on a knock-out basis rather than groups. The 24 teams qualified were divided into six groups of four (A to F). The top two teams and the four best third-place finishers from the six groups advanced to the knockout round of 16 teams. Italy were the defending champions, but were eliminated by France in the Round of 16.
The 1986 World Cup saw the appearance of an audience phenomenon dubbed the Mexican wave, which was popularised worldwide after featuring during the tournament.
