Much to everyone’s disbelief, the Leicester City soccer club was crowned the champion of the English Premier League Monday.

The team’s chances last summer were small, to say the least. Back then, William Hill, a British betting group, put the odds of the Foxes of Leicester City, a fledgling team based two hours north of London, of winning at 5,000-to-1. Essentially, the team had a .0002 percent chance of being the best team in the league of 20. Except for the 25 people who bet a combined total of just $243 on the team through William Hill, no one expected this from Leicester City.

Here’s some perspective: William Hill once put the odds of Elvis being found alive and well at 2,000-to-1 and an acknowledgment by the U.S. government that the first moon landing was faked at 500-to-1.

And some more perspective, from ESPN:

Not only did the Foxes have a 13-game winless run last season, they were only six points from being relegated to a lower level of competition. Leicester City wasn’t even in the Premier League two years ago. The club earned promotion to England’s top soccer league starting in the 2014-15 season for the first time in 10 years.

In the world of overused sports tropes, declaring a victory “one of the biggest upsets in history” is a frequent sin. But in this case, this is the biggest upset in modern sports history.
