The Reds are back on Merseyside after their trip to Qatar, where they beat Monterrey and Flamengo to lift the club’s first-ever Club World Cup.
They return to Premier League action on Boxing Day as they take on Brendan Rodgers’ second-placed side at the King Power Stadium.
Victory for Liverpool could put them thirteen points ahead of their closest rivals, with a game in hand against West Ham to come later in January.
Klopp warned that it would be no easy feat, however, with the boss praising the job Rodgers has done while at Leicester.
"They have the highest quality with all the things: desire, hard players, aggressive challengers, super footballers," Klopp said.
"The wings, creative, quick... then you have Jamie Vardy on top of that and Maddison in between.
"Brendan has done an excellent job there and they are a proper top-class team.
"In this situation, where people talk about them a little bit like 'how did they come there?'
"But the quality they have are exceptional, plus the manager they have is a really good mix.
"Apart from that, we will prepare like we always do."
Despite the festivities surrounding the fixture, Klopp backed his players to have the right focus to deal with the game, as they have done all season.
"We have only highest-quality players. It’s not the biggest group, it’s a small group and getting smaller week by week. But so far we could deal with it," Klopp said.
"To come through a season you need to be lucky in these moments that you can bring on a team which can win a game. That’s what we try to do."
"What we have to make sure and what we try to do since I’m in, is how we can respect the social things like Christmas—we have to; first and foremost, we are human beings and there are family at home, stuff like this.
"We try to do all the important stuff football-wise around [these things]. That’s what we always did and do this year.
"Apart from that, the boys need to be smart enough to do the right things as well. What you all probably do at Christmas is for us not exactly the same; we still have to eat the right things, not what everybody else eats!
"That’s the only real difference. Apart from that, we prepare the football game and the boys are focused enough to do it in the right way."
