Keita was one of the Reds' top targets during the summer after the midfielder helped Leipzig finish second in the Bundesliga last term.
Liverpool eventually announced an agreement to sign Keita at the end of the current season and it has since been suggested the German outfit may be willing to allow the 22-year-old to head to Anfield in January.
Leipzig sporting director Ralf Rangnick has now moved to end any speculation surrounding Keita by ruling out an early exit, as he says the Guinea international is integral to their plans for the remainder of the season.
"Even if we should not reach the knockout stages of Champions League, it would make no sense to allow Naby to join Liverpool earlier," Rangnick told Leipziger Volkszeitung. "We want to qualify for Europe again and we need Naby for that."
Leipzig are second in the Bundesliga standings, with 22 points after 11 games, and third in Champions League Group G, two points behind second-placed Porto after four matches.
