The Black Cats came from a goal down on two occasions to beat Chelsea 3-2 in an epic encounter at the Stadium of Light which saw the North-East side take a massive step toward safety.
Sam Allardyce's side sit 17th in the table, one point ahead of Newcastle United in 18th and four clear of 19th-placed Norwich City.
Sunderland get their game in hand out of the way on Wednesday for the visit of Everton, a game they go into knowing that victory would relegate their North-East rivals and of course the Canaries.
And the former Liverpool man, who scored to make it 2-2 against the Blues yesterday, has urged the Sunderland fans to get them over the finish line once again.
"(The crowd were) unbelievable, and we need that again on Wednesday because that made the difference when we went down 2-1 and kept us going," he said via BBC Sport.
Allardyce and co face Watford away in their final game of the season next Sunday.
