Sunderland has some bitter history with their play-off rivals Coventry City.
Cast your mind back to 1977, when there were three teams in danger of relegation from the old First Division: Sunderland, Coventry and Bristol City.
Sunderland lost to Everton and were awaiting the result of Coventry v Bristol City, which had been delayed due to traffic issues around the Sky Blues' then home ground, Highfield Road.
As the Black Cats had been defeated, a draw would be enough to keep both the Sky Blues and the Robins up, while a loss would send either team down.
