5. South Korea 2-1 Italy (2002)
Despite four successive winless group-stage exits between 1986 and 1998, confidence amongst hosts South Korea hinted at a shock in the 2002 tournament.
Roared on by a fanatical home support, Guus Hiddink's side topped their group, with impressive wins over Poland and Portugal.
However, a showdown with Italy in the last 16 looked to be a major test of their capabilities, as Hiddink's side survived a barrage of Italian pressure.
The host nation stayed in the game, as Italy struggled to build on their 1-0 lead, before Seol Ki-hyeon's equaliser forced extra time and Ahn Jung-hwan's golden goal won it.
Despite the huge acclaim for South Korea's shock, the post-tournament chat was dominated by allegations of corruption in their subsequent quarter-final win over Spain.

Valery Nepomnyashchy's side were eventually knocked out by England in the last eight, as they broke new ground for African nations at the World Cup.
3. Argentina 1-2 Saudi Arabia (2022)
Argentina were fancied for the title by many when they arrived in Qatar as Copa America winners under the captaincy of seven-time Ballon d'Or winner Lionel Messi.
Against a Saudi Arabia team ranked 48 places below them in the FIFA rankings, Lionel Scaloni's side made an ideal start when Messi converted a 10th-minute penalty.
There were few signs of danger until Saleh Al-Shehri slotted in with 48 minutes gone. Five minutes later, the shock was on when Salem Al-Dawsari's stunning strike sent the green shirts in the crowd into delirium.

Senegal took full advantage of France's stage fright. to announce themselves on the World Cup stage, through Papa Bouba Diop's iconic winner.
1. USA 1 - England 0 (1950)
It was dubbed the, "Miracle on Turf". The United States had lost seven straight international matches by a combined score of 45-2 coming into this one, so you can easily see why they would have been considered the underdogs.
However, the English players were a little too cocky for their own good. But this was America's only win at the World Cup that year, but who cares.
Despite only making their World Cup bow at the 1950 World Cup in Brazil, England were tipped to upset the established order, against an unfancied United States side filled with part-time players.
