The Black Cats can secure yet another late escape with victory over Everton on Wednesday night.
Sunderland manager Sam Allardyce has said, as quoted by the Mirror, that it has been his side's ability to secure valuable draws rather than slipping to defeat which has kept them afloat in the Premier League this season.
The Black Cats can secure their survival for another year - and send Norwich City and arch-rivals Newcastle United into the Championship - with victory over Everton at the Stadium of Light on Wednesday night.
After Saturday's euphoric 3-2 win over Chelsea, in which the hosts came from 2-1 down with 25 minutes remaining to grab a priceless three points, Allardyce's side have now lost just one of their last nine league fixtures.
Of those, six have been draws, with the Wearsiders twice scoring injury-time equalisers to salvage a point, and Allardyce says it is that resilience in not surrendering to defeat which has enabled his side to move to the brink of safety.
The 61-year-old said, as quoted by the Mirror: "We’ve drawn too many games we should have many more won than we have. But only losing one in nine is one of the reasons we’ve got to the position we’re in.
"We should have secured our Premier League status earlier but although we’ve thrown those opportunities away we’ve still secured a point and another point and another... and another point and then three points."
If Sunderland can record just a fourth win since January on Wednesday, they will continue their trend in recent years of pulling out of trouble in the final weeks of the season.
If they are not able to secure victory they will still be in pole position, as a draw or defeat would leave Newcastle needing to beat Tottenham Hotspur on the final day coupled with a Black Cats defeat at Watford.
