Tony Pulis insists he still has "great belief" that Stoke will save themselves from relegation.
And he will be boosted by the likely return of giant striker Mamady Sidibe for Saturday's survival battle with Portsmouth.
Pulis said: "I still have a great belief that we will avoid relegation. Very much so. We need our injured players back and we don't need any other injury problems in this situation."
He added: "We have 13 games to stay up and everything has to go for us now."
Sidibe made a big impact earlier in the season but has not played since December following a knee injury.
Ricardo Fuller could also return from injury far quicker than expected but Pulis has serious doubts over on-loan Irish defender Stephen Kelly, while Rory Delap and Matthew Etherington are suspended.
Fuller, who was carried off at Sunderland a fortnight ago with a dislocated shoulder, was expected to miss most of the rest of the season but has been back in training this week.
Pulis added: "We could have Sidibe back. He is very much in the frame for the weekend.
"He has been an enormous loss to us. He will need time and we can't expect him to be back to what he was just yet.
"Fuller looked to be out for a long time with a dislocated shoulder but he has trained a couple of days this week on his own, which has surprised me, so we will see how he is at the weekend. We are now hoping he will be back quicker than we thought, but probably not for this next match."
