David Ngog struck the only goal as Liverpool unconvincingly edged out a fired-up Leeds side 1-0 in the Carling Cup.
The Premier League giants were outplayed by the League One leaders for much of the third-round tie but Ngog netted against the run of play after 65 minutes.
Leeds spurned a number of chances throughout the game as Elland Road enjoyed a big-game atmosphere once again but their lack of composure in front of goal cost them.
