Palace boss Dougie Freedman refused to give any excuses after seeing his side give away a 2-1 lead against Watford in the last five minutes.
"That last ten minutes was obviously disappointing but looking back at the performance I don't think we did enough to win the game. I thought we probably did enough for a draw but when it went two each the momentum was with them. Of course it's disappointing to lose the match in the last five minutes but it was a great effort from the lads.
"The heat was a factor, yes, but it's the same for both teams, there's no excuse. Both sets of players felt it. At 2-1 up we had a couple of half chances that could have killed the game but we were hanging on at the end. It's disappointing but it's a challenge for us that we've got to bounce back from. We just didn't defend as a whole well enough at the end to come away with the three points."
Watford's two late goals were scored by recent signings and the Palace boss was asked about his own work in the transfer window to date.
"A couple of our players do need time to settle in but as a defensive unit we've got to be better than that to win games. I felt that in the last ten minutes of the game we didn't really focus on our jobs as well as we should have. There isn't an excuse as to why, we'll assess it, we'll look at the video and we've got to move on quickly."
Injury-wise Palace were without captain Paddy McCarthy and young Jonny Williams and Freedman explained their absences from the squad.
"Jonny Williams has a calf strain, it's a result of his broken leg last year, he keeps on picking up little injuries. We just need to be careful with him - maybe another week or so. Paddy's groin is playing up, he felt it in the Reading game. We've just got to be strong, there's no use us throwing them in there when they aren't at their best. When they come back they'll come back stronger."
