We’ve taken a look back at the last two decades in the third and seen where the losing play-off finalists have finished in the season immediately following their promotion heartbreak. And while it was bad news for some, the Black Cats could be encouraged by the performances of some of their predecessors - and will be hoping that history repeats itself this season. Scroll down and click through the pages to see how the history books suggest the Black Cats will fare, if previous play-off finalists are anything to go by:
17. 2001/02: Brenford
Stoke City were the play-off victors in 2002, leaving Brentford in their wake. The Bees struggled the following year and settled for a bottom half finish. Finished the year after play-offs: 16th. Photo: Harry Murphy
18. 2000/01: Reading
Another fine lead for the Black Cats to follow, Reading were beaten by Walsall in a thrilling clash in 2001 before sealing an automatic spot the following season. Finished the year after play-offs: 2nd (promoted). Photo: Charlie Crowhurst
19. 1999/2000: Wigan Athletic
A goal two minutes from the end of extra time denied the Latics promotion in 2000, and they would suffer more play-off heartache the following season. Finished the year after play-offs: 6th. Photo: Daniel L Smith
20. 1998/99: Gillingham
After THAT final with Manchester City, the Gills could have been forgiven for having some play-off nerves - but they shook them off the following season. Finished the year after play-offs: 3rd (promoted via play-offs). Photo: Alex Broadway
