Leicester won the 2015–16 Premier League, their first top-level football championship. They are one of only six clubs to have won the Premier League since its inception in 1992. A number of newspapers described Leicester's title win as the greatest sporting shock ever, considering at the start of the season they were favourites to face relegation. Multiple bookmakers had never paid out at such long odds for any sport. As a result, the team was dubbed "The Unbelievables", a spin-off harking back to Arsenal's undefeated team "The Invincibles". The club's previous highest ever finish was second place in the top flight, in 1928–29, then known as Division One. Throughout Leicester's history, they have spent all but one season in the top two leagues of English football. They hold a joint-highest seven second-tier titles (six Second Division and one Championship).
