First some facts. Since the Premier League began in 1992, Leicester City have been part of the competition for 11 of its 25 seasons.
They have been relegated three times, twice after just one campaign (1994-95 and 2003-04); their longest unbroken spell in the top flight is six seasons (1996 to 2002). To give the last figure context, Wigan (eight seasons) had a longer consecutive stint as a member of the elite in this era.
Now let's go back even further and look at the final 25 years of the old First Division. Leicester's performance was slightly better; they spent 14 seasons in the top flight but there were still four relegations.
