Wayne Hennessey felt Palace's performance against Chelsea merited more, insisting that on another day the Eagles could have snatched a big point off the Premier League leaders.
"I thought we played really well at times and on a different day we could snatch a goal and get a draw out of it," he said. "Fair play to the boys we did really well, but not enough to get a result."
It was a Diego Costa header late in the first half which sealed the 1-0 win for Antonio Conte's side, with the big forward out-jumping Scott Dann and guiding Cesar Azpilicueta's looped ball over Hennessey.
"He's on fire at the moment, so any little error or anything like that and he'll punish you, unfortunately that's what happened," the goalkeeper said of the Spain striker.
"We've got a great dressing room and hopefully when the next game comes we can turn over [a new leaf] and get the three points and start climbing up the board.
"That's a must-win for us really. We'll prepare ourselves now, recover and hopefully be ready for that game."
Hennessey has been hailed for several superb stops in the defeats to Manchester United and Chelsea, but he revealed that though the praise feels good, clean sheets are what top flight goalkeepers crave.
"Every goalkeeper makes saves and you want to play to the highest ability that you can, but clean sheets are what you want to try and get out of a game," he said. "Hopefully I can get that next time out."
