4. South Korea beat Italy 2-1 (2002 World Cup):
Circa 2002, Italy were to face the other Korea, South Korea in their last-16 fixture at Daejeon. Trailing to an early Christian Vieri goal, the Koreans launched an astonishing comeback, and equalised through a last gasp goal from Seol Ki-Hyeon. From then on, it was Korea all the way, as Francesco Totti was sent off in extra time for the Italians and Ahn Jung Hwan scored the ‘Golden Goal’ to send the entire nation in raptures. After beating Italy, Korea beat another heavyweight Spain in the quarter finals, before losing to Germany in the semi-finals.
The other memorable upsets include Greece’s Euro 2004 miracle victory over Portugal and a Roger Milla inspired Cameroon beating Argentina in the 1990 World Cup, but the writer feels the above mentioned matches surely deserve good mention.
