The Reds will step out onto the field in front of a full group of supporters after last year's 1-1 draw behind closed doors against Marcelo Bielsa's side.
Liverpool have taken seven points from a possible nine so far in the 2021-22 Premier League season, but Klopp is aware that his side will have to perform at their best in order to come up trumps.
Speaking to the press ahead of Sunday's game, Klopp said: "Everybody tells me that the atmosphere is absolutely outstanding so I'm looking forward to it.
"We have some people who can tell us how it will be with Milly (James Milner) but the game itself is already tricky, we saw it in the last two games we played against them, it was really exciting.
"They obviously have a specific way of playing the game with a strict man marking philosophy or idea and very flexible, brave and dynamic in possession. It's a really good football team and we have to be at our best to get something there."
Liverpool will not be able to field Alisson Becker, Fabinho or the injured Roberto Firmino on Sunday, but Klopp has revealed that Virgil van Dijk is fine to play after an injury scare with the Netherlands.
