The Black Cats sit 15th in the table, five points clear of the relegation zone with 11 games remaining.
The Sunderland manager told the club's website: "Following the Wigan game we were on a high but had a stodgy game against Swansea at the Stadium of Light followed by three fixtures I feel we should have got something from.
"One result can inspire confidence and they will feel they are capable of taking on anyone, but it really is up to us. We have the wherewithal and the drive and determination to see this last third of the season through as strongly as possible.
"If we can create the same number of decent chances against Fulham, then we just have to hope that little bit of luck and finesse doesn't elude us and we can score a few goals."
Sunderland host Fulham in the Premier League tomorrow.
