Ricky Sbragia says he wants to stay on as Sunderland boss but knows he will be on his way if he fails to keep the club in the Barclays Premier League.
The Scot, appointed as a safe pair of hands by Sunderland chairman Niall Quinn after Roy Keane's shock departure in early December, admits he did not expect to be involved in a last-day survival fight.
But he knows victory over Chelsea at the Stadium of Light on Sunday guarantees at least one more season of top-flight football and insists his side will not go down.
Sunderland have won five of Sbragia's 22 games in charge, and four of those were in the first two months. They have lost key matches over the last six weeks.
Sbragia, who has a year left on his contract, insists he wants the job full time, but prospective owner Ellis Short is known to be looking further afield for a replacement, with Celtic boss Gordon Strachan favourite for the job. If the club do go down, they are likely to lose striker Kenwyne Jones, who claims he will move on.
