Jürgen Klopp's men set up a semifinal clash with Manchester City after Diogo Jota netted the lone goal of the match 12 minutes from the end at the City Ground as Liverpool earned a 1-0 victory over Nottingham Forest.
The game began at a fast pace with both sides exchanging attacks in the opening period. Forest posed the first threat in a game which failed to settle into a rhythm after the first whistle, as Joe Lolley had his low cross cleared at the last moment by Naby Keita.
Forest worked a strong chance to open the scoring entering the final 15 minutes, but Philip Zinckernagel failed to score from the penalty spot as he watched his strike fly past the far post.
Jota's late strike proved enough to see Klopp's outfit edge into the final four for the first time under the Reds boss, with City up next at Wembley.
