Liverpool started the season strongly, with a 4-0 win over West Ham, putting themselves at the top of the table.
However, Klopp has insisted that his side should not get complacent, and they will go in hard against Roy Hodgson's side.
"We need to make sure that we are really ready for them after all the positive stories during the week," he said in a press conference.
"That is probably the biggest challenge because people still aren't used enough to good football from us so when we are good they say, 'you're unbelievably good' but we haven't gotten anything for it so far. So, we need to stay positive but we also have to stay angry as well and not celebrate the whole week only to fall on Monday."
"But it's nice, it could be completely different. We have said that we are in a good moment but we are still in a process."
"We have to develop. We are not the best team in the world so we have the space to improve in all the different departments and that is what we try to do."
"That is very important because we are not alone, our supporters like the way we do it and that is very important. We feel it is a healthy situation at the moment."
"We need to be ready for everything that happens in a season but West Ham was nearly perfect. We defended really well. The boys were really spot on and we need to be spot on again [against Crystal Palace]."
