Palace remain in the bottom half of the table after defeat to Chelsea.
Hodgson said, “We need to make certain that we never lose sight of the fact that is doesn't really matter where you are at Christmas. Last season we were very rarely outside the relegation zone and we ended up in 11th, and could have even been 10th if it wasn't for goal difference.
“There's an awful lot of football to be played, but the one thing you do know as a manager is that if your team are playing badly and not getting points, you never really have any confidence as to where points will come from.
“I'm not in that position – we missed chances, been unlucky and not have as many points as we should have, but let's see where we are after 38 games, and the important thing is to keep going, regardless as to what happens in the next two."
