There are some big clubs at the bottom of the Premier League.
Among them are an ever-present and a former champion. If Leicester go down, seven years after their title win, they would be the first top-flight champions to be relegated since Blackburn in 1999.
Three of the last five champions to go down did so within six years.
Everton are one of six Premier League ever-presents while only Arsenal have enjoyed a longer consecutive run in the top flight.
120 No club has spent more seasons in the English top flight in their history than Everton (120), ahead of Aston Villa (109) and Liverpool (108).
