Alan Pardew said that his players were unfortunate not to come away with anything from the defeat against Watford, even after a disappointing opening period of the game.
"It was a tough result for us. We couldn't get going in the first half, we were much improved in the second half and should have won it, so it's a bit of a blow to lose the game.
"We made a slight error on the Watford winner. I can't think of too much of a threat they had in the second half, but that is what it is for us. We are on a tricky run and need to fight out way out of this form."
Referee Robert Madley gave an early penalty against Mile Jedinak and the manager believed he has seen similar challenges against his side go unpunished.
"We have had situations where Scott Dann is dragged to the ground on regular occasions but nothing is given. I am not going to say it was not holding, but to have it on the first corner at the first play was tough.
"Things go against you when you are on the type of run we are but we just have to focus and even though the league form is a bit of a worry, we just have to put it right.
"It is a 90-minute game and we wasted 45 minutes."
When asked for a reason as to the first half disappointment, Alan felt it was down to the balance of the side.
"That was as poor and unbalanced a side as I can remember putting out for Palace, it just wasn't happening for us.
"Too many long balls, it was a bit worrying if I'm honest. If I thought there was a complacency or lack of effort, that would really worry me. The things that worry me are technical issues, like the balance of the team, and making sure we dominate games, particularly against teams like Watford.
"The boys' reaction after half-time was about as good as I could hope for. As I say we were a little bit unlucky to have lost this game."
