Even heroes have off days. There are some times when Superman just can't be bothered or Batman would rather just sit at home reading a book. And as Palace lost 1-0 at Manchester United on Saturday, it was down to a rare error from the Eagles' goalkeeper Julian Speroni.
The four times Player of the Year probably should have done better with a Juan Mata shot in the second half which he flapped at, resulting in the winning goal. Mata's shot took a deflection and this almost certainly made it trickier to save but "Jules" probably should have got more of a fist on it.
But he's been such a hero for so long for the Palace faithful that it's difficult to feel angry towards him. In fact there's no real point because knowing what a proud and passionate player he is, he probably feels enough anger towards himself right now anyway.
He loves Palace as much as the fans do and losing hurts him like it does any of the 2,000 or so Eagles supporters that made their way to Manchester on Saturday (and again gave the home fans a lesson in singing for your team).
Speroni has been at Palace for so long and dug the team out of a hole so often is doesn't matter if he has the odd slip up. In fact, he could score 100 own goals in one match and Palace fans would still love him.
He's already earned the team points this season with some great saves. Take the Burnley game at home where Palace struggled to break down the worst team in the league and were heading for a goalless draw when the Clarets were awarded a penalty in the final few minutes. Scott Arfield stepped up but Speroni was equal to him, beating the ball away with a wrist so strong it could have been made of iron.
That iron wrist was missing at Old Trafford on Saturday and it turned out to be the decisive moment of the game which United went on to win 1-0. That tells you much about the game; it wasn't a walk over, Palace were always in it.
Palace's wingers also had an off day. Yannick Bolasie and Jason Puncheon have the ability to be deadly but they were below-par. It meant striker Fraizer Campbell had an afternoon of just running and running without much reward.
This performance was much more like the organised set-up that we saw under Tony Pulis last season and Campbell's missed one-on-one against David De Gea with the score 0-0 was perhaps the turning point.
Maybe Palace just need to go back to basics like they did under Pulis. Sort the defence out (which is getting better) and then take things from there. United had more possession and chances but Pulis' Palace would have probably got a result from that game against a team low on confidence.
The only question marks are around manager Neil Warnock's substitutes. The game was crying out for Dwight Gayle but the Palace manager waited until the final 10 minutes to bring him on. It's so hard for a striker to get into a game at that level in just the final few minutes and Gayle really does deserve more of a chance. He would have buried that Campbell chance in the first half.
But things are getting better. And with Wilfried Zaha and Mile Jedinak to come back in, no-one should be getting too worried yet.
