Sunderland manager Ricky Sbragia is urging his players to finally take the chance to confirm their Barclays Premier League status.
The Black Cats remain in 16th place in the table after Saturday's fixtures, but are only a point clear of Hull in 17th and one more better off than derby rivals Newcastle inside the drop zone.
As a result, they need a win at Portsmouth to guarantee their top-flight survival, with a draw still leaving open the possibility that Newcastle could move above them on goal difference if they beat Aston Villa on the final day and the Wearsiders are beaten by Chelsea in their last game.
Sbragia said: "We know what we have got to do. We have had nine or 10 weeks to do it and we haven't quite done it.
"But the Bolton game, we definitely, without a doubt, got a good performance and we needed that, to be truthful with you.
"It was a good, valuable point as well and if we had our shooting boots on, we might possibly have got a win. We knew it was going to be very difficult, but we surprised a few with how we dealt with the situation."
