Sunderland boss Gus Poyet says beating the drop will be the "biggest" achievement in his career.
In recent weeks, Sunderland have won at Chelsea and Manchester United, and drawn at Manchester City in a remarkable revival - prompted by their manager's positive team talks.
Poyet said: "For me in particular it will definitely be my biggest achievement. I have no doubt because it's been difficult, I can tell you that.
"Normally, you don't celebrate when you finish 16th in the league. We will.
"If you said to me before the Man City game that we would be here talking like this I would have said you had been drinking heavily before you came. It's incredible.
"We can use different words but the last four games has been amazing. Any stage of the season it would be incredible but that's why it is so important to finish the game somehow.
"I'm trying not to praise myself. I just believe in what I do and the best way is to convince the players. If you can get to the players, even if they don't like it if they understand why and there's a reason they will go with you."
