Sunderland's on-loan striker Nicklas Bendtner is adamant their new-found confidence will not have been punctured by Saturday's defeat against Chelsea.
Frank Lampard's early goal was the difference between the two sides and truncated the Black Cats' five-game unbeaten run.
It was only the second time Sunderland had failed to score during Martin O'Neill's eight-game reign, and the Denmark international urged his team-mates to stay positive.
"I wouldn't say we've gone backwards or anything," he told The Chronicle.
"We've lost a game, perhaps unfairly, but those things happen sometimes. If we can keep playing like we did on Saturday, then it looks really bright.
"We were a bit unfortunate at not getting the ball in the goal."
The defeat leaves Sunderland 12th in the table but the former Birmingham loanee insists they are already looking ahead to their next game this week, where they hope to make amends for this defeat.
He added: "We created some really good chances and played some good stuff, but for some reason it didn't go our way.
"We did really well in the game and should have got something out of it. Everyone was really disappointed with it.
"There were a lot of positives to take from the game and we've got to take that, even though the disappointment afterwards was huge. But we'll look at it this week with brighter eyes."
