Connor Wickham was frustrated that his two goals weren't enough to get Palace anything against West Bromwich Albion.
A poor opening half an hour saw the visitors trail by three goals, and a much better performance from Alan Pardew's side after half-time saw the striker bag an impressive brace - his first goals from open play for the Eagles.
However they were in vain as Palace failed to end their search for a league win which stretches back to December, and Wickham regrets getting off to a slow start against the Baggies.
"It's massively disappointing the way we played in the first-half," he said. "It was unacceptable and the gaffer told us that at half-time.
"In the second half we went out there and performed nowhere near our best but we got two goals back and could have got ourselves back into it, but the first half an hour cost us.
"We'll have to analyse why; the manager will have us in and put us right but we have a game coming up very soon so we have to focus on that.
"I wouldn't say confidence is an issue, we've suffered a lot with injury recently but they're starting to come back with and we've got to start getting back to playing our best and pick it up again."
Wickham faces his former club in Sunderland on Tuesday night aiming to build on his confidence in front of goal, and he revealed that Pardew has helped him to relax in front of goal, something which has evidently worked for the hitman.
On his brace, he added: "It's a weight off my shoulders personally but the gaffer has spoken to me individually over the past few weeks and said there's no pressure on me to get goals.
"I always want to score goals and I'm pretty pleased tonight that I've got two. It wasn't enough but hopefully it can be a confidence builder for the rest of the season.
"It's just me going back to instinct, I've thought to shoot every time and thankfully I've caught the second one sweetly and it's gone into the top corner."
