The defender, who once again wore the captain’s armband in Saturday’s 3-1 win away to Wolverhampton Wanderers, is one of many Palace players in outstanding form of late.
The victory, which arrived courtesy of goals from Michael Olise, Jean-Philippe Mateta and Ebere Eze, was Palace’s fifth in their last six matches, with Andersen saying: “We've been getting some really good results lately and playing really, really well.
“I don't think today was our best performance of the games we’ve played, but then we showed also fighting spirit, we showed we can score from our chances even though we could have scored even more. Then, they got back into it, and we showed a good reaction again to score and finish the game really.
“At the moment, we have a lot of confidence and everyone is working so hard, which makes it so much easier for everyone and that makes it so hard to play against us.
“The way we press, the way we are so compact, everyone is squeezing up, there's a short distance between the lines. It's really good, and then we have some really good players who can finish off the attacks.”
