Midfielder Mike Jedinak says Crystal Palace have to bounce back quickly from their defeat to Manchester United.
Palace have fellow strugglers Swansea next up on Sunday in what looks a crunch game for both clubs.
The defeat to United was only the second time they have lost at home since Tony Pulis replaced Ian Holloway in November.
But they remain just two points above the drop zone after the 2-0 defeat at Selhurst Park.
"We had them under a little bit of pressure before that first goal so we'll take a lot of positives from that," Jedinak said.
"We've just got to keep building. The word 'disappointment' comes to mind, but it was encouraging nonetheless.
"It was a defeat, but we let them off the hook a bit. We gave them a penalty through a challenge which was probably a rash decision at the time. Those things can happen in football.
"Our next game is on Sunday against Swansea away so we've got to regroup, regather, put this out of our system and keep building.
"There is not time to feel sorry for yourself. We will pick each other up, dust it off and get right back to work."
