There has been animosity between the two sides, and sets of fans, for the best part of a decade, but Klopp likes to think there is some form of mutual appreciation.
"I know about our respect for Chelsea and I am pretty sure from the other side there is exactly the same," he said.
"They've seen us playing and they know we are not easy to play and that is what I thought most about in the last two days and what I will think about because there is always a way to create moments which you are not expecting.
"The problem is they maybe have the same plan.
"They were champions two years ago and then had a difficult year and they changed their manager.
"Last season was not a Chelsea season and now they are back on track, so we need to be ready for a real challenge."
