He said: "I don't think it's a general low point, but you can see performance-wise it was a low point.
"The good thing about a really bad performance is that you can play better, so we should start from there (against Palace). First and foremost, this must feel bad and it does."
Klopp added: "We have to show a reaction, definitely. That is 100% clear. I will think about that but it's not the first time in my life that I lost a football game, unfortunately. We will show a reaction, I can promise."
He also said of team rotations: "It is not pressure, it is just the situation.
"My job is not the easiest job in the world - it is not the most difficult as well - but when you have players you need to make sure you get them on the pitch."
