The Reds came back from a goal down to beat Fulham 2-1 at Anfield, leaving them in touching distance of another Wembley cup final.
When the Carabao Cup last four draw was made, many expected a final that would be a repeat of the 2022 edition between Liverpool and Chelsea.
On Tuesday, however, 2004 winners Middlesbrough showed that games are not won on paper.
The Riverside erupted as the Championship side defeated the Blues by a goal to nil in the first leg of the first semi-final.
At the interval in the second semi-final on Wednesday, the expectant Anfield crowd would have felt just as shell-shocked as their big six rivals.
Former Chelsea man Willian got the goal that put Fulham in front, leaving Jurgen Klopp a frustrated figure on the sidelines.
As they had done on so many occasions this season, though, the Reds bounced back to rescue a win after the break.
The introductions of Darwin Nunez and Cody Gakpo did the hosts the world of good as the duo combined for the winner after Curtis Jones levelled matters in the final quarter.
Both ties are far from over; and even with major upsets just one game of football away, Liverpool will certainly feel the most confident of progressing.
The second legs will take place on 23 and 24 January.
