The qualification process for the final round of the men's football tournament at the Olympics explained...
Men's football in Olympics started in 1900 in France where London-based now-defunct club Upton Park FC, representing Great Britain, had won the gold medal.
Since then, football has been played in 26 editions at the Olympics. 1932 Los Angeles Olympics was the only edition where football was not played as reportedly FIFA wanted to promote the World Cup which started in 1930.
Hungary and Great Britain (including Upton Park's triumph) are the most successful teams in the history of the Olympics with three gold medals each followed by Argentina, Uruguay and the Soviet Union, who have two golds each.
