Odds and Answers
Ten questions we hear most from fellow underdog enthusiasts, answered with the record books open and the myths politely set aside.
What makes a result an upset rather than a surprise?
An upset needs a measurable gap before kick-off: league tier, world ranking, budget, recent form or betting odds. A result that only looks shocking with hindsight is a surprise. We file a match only when the evidence from before the game says the winner should have lost.
What is the biggest upset in World Cup history?
No official ranking exists, and anyone who claims one is selling something. The strongest candidates are USA 1–0 England (1950) and North Korea 1–0 Italy (1966), both rated 9/10 in our World Cup file. Saudi Arabia 2–1 Argentina (2022) is the strongest modern contender.
What odds were Leicester City to win the Premier League?
Leicester were widely quoted at 5000–1 before the 2015–16 season, having been bottom of the table in April 2015. They finished on 81 points, ten clear of Arsenal, and bookmakers paid out to the handful of punters who believed.
Has a non-league club ever won the FA Cup?
Once since the Football League was founded in 1888. Tottenham Hotspur, then a Southern League club, beat Sheffield United in the 1901 final after a replay at Burnden Park, Bolton. Non-league clubs have reached later rounds since, including Lincoln City's quarter-final in 2017, but none has repeated the feat.
Why do cup competitions produce so many upsets?
A single match removes the league's safety net. The smaller club often hosts, on a tighter pitch in front of its own crowd, and the favourite frequently rotates its squad to protect league ambitions. See the cup file for six examples.
Which team won a tournament it did not originally qualify for?
Denmark at Euro 1992. They finished behind Yugoslavia in qualifying, were admitted when Yugoslavia was excluded under UN sanctions shortly before the tournament, and beat Germany 2–0 in the final in Gothenburg.
Why is football more prone to upsets than other sports?
Goals are scarce. In high-scoring sports, the better team's quality accumulates over many scoring events; in football, a handful of moments decide most matches. Chris Anderson and David Sally's book The Numbers Game (2013) argues that chance accounts for roughly half of match outcomes, which would explain a great deal.
Has a newly promoted side ever won a top-flight title?
Yes, though rarely. In England, Ipswich Town (1961–62) and Nottingham Forest (1977–78) did it. In Germany, Kaiserslautern (1997–98) remain the only promoted side to win the Bundesliga. All three are in our title file.
How is the underdog rating calculated?
It is an editorial score from 1 to 10 weighing four factors: the pre-match gap, the stakes, the manner of victory and the result's legacy. The pre-match gap carries the most weight. The full method is on our About page.
