Senegal knew they would be playing the hosts and current European champions France in the opening match of the 2002 World Cup, their first-ever appearance on the world's most significant international stage. Thierry Henry, Patrick Vieira, Marcel Desailly, Lilian Thuram, and Fabien Barthez were the Frenchmen in the starting lineup. Despite the absence of Zinedine Zidane due to injury, the club should still have been capable of defeating a side whose sole notable player was a youthful El-Hadji Diouf.

Instead, France struggled to get into a rhythm, and after 30 minutes, Papa Bouba Diop, subsequently of Fulham and Portsmouth, scrambled in the game's lone goal. Senegal reached the round of eight while France was eliminated in the group stage, tying an African record.

Top 10 biggest upsets in sports history: Best underdog wins (8)

Liverpool needed Luis Garcia's "ghost goal" in a tense match against Chelsea, incredible defence from Chelsea, and a lot of luck to advance to the Champions League final in Istanbul in 2005. It was widely anticipated that Milan, who had players like Andriy Shevchenko, Kaka, and Clarence Seedorf, would have an easy time of it. Few were astonished when the Rossoneri left the field with a three-goal lead at halftime since everyone assumed they had finished cruising to their seventh European Championship.

Legend has it that at the half, a stirring rendition of "You'll Never Walk Alone" could be heard in the Liverpool locker room, and the Reds quickly began to battle back. The game entered extra time after scoring three goals in the final six minutes, and Jerzy Dudek emerged victorious in the ensuing penalty shootout.

The 1980 Winter Olympics were held in Lake Placid, New York, and the Soviet Union, one of the strongest teams in the world, was scheduled to play the American National Ice Hockey Team. The Soviet Union team was at its best, with highly skilled, seasoned players, and had been winning medals for years.

On the other hand, the American squad was made up of unproven college players and other players who did not have excellent reputations. One of the nation's proudest sporting moments will always be the victory over the Soviet Union at Lake Placid.

However, as is sometimes the case in the FA Cup, Wigan's enthusiasm and drive prevailed on this particular day. Throughout the 90 minutes, City struggled to get going and could only stay in the game because Wigan did not take advantage of their opportunities. Fortunately, the Latics did not suffer the consequences, as Ben Watson's game-winning goal in stoppage time ultimately materialized.

Tyson was on fire during his heyday, giving his opponents knockout after knockout. Most observers predicted Tyson would easily defeat Buster Douglas that evening, and the odds against Douglas were over 50-1.

After the encounter between the two nations, practically all football enthusiasts kept asking themselves, "What were Saudi odds to beat Argentina?" Lionel Messi's quest to finally win the World Cup was the topic of conversation leading up to this Group C opening, and a victory over Saudi Arabia was presumptively expected. Despite Argentina's three goals being disallowed for offside and Messi's early penalty, the underdogs competed admirably and completely changed the game in the second half.

Salman Al-Faraj restored parity before Saudi Arabia's skipper Salem Al-Dawsari gave his team the lead moments later, sending jaws dropping worldwide. Argentina struggled mightily but ultimately failed to equalize as Saudi Arabia pulled off what is likely ranking the biggest World Cup upset of the twenty-first century.
