Liverpool produced the kind of display that so many said they couldn't in the Stadio delle Alpi to force their way into the Champions League semi-finals as they held pre-tournament favourites Juventus to a 0-0 draw to progress 2-1 on aggregate.
They fought like men possessed, deep in defence but never in panic and Juventus were reduced to almost a standstill as time after time the waves of Juve attack crashed on the rocks of the Red defence.
The heroes were Jamie Carragher, Steve Finnan and Sami Hyypia at the back, Xabi Alonso in midfield and tireless battlers like John Arne Riise and Igor Biscan.
But the triumph belongs to boss Rafael Benitez, who somehow produced a game plan to defy a team that many called the best in Europe.
Milan Baros was a constant menace to Juve's defence in the early exchanges, but although his pace and movement caused plenty of concern for Montero and his ageing legs the Czech international lacked support in good positions.
Juve's tigerish midfielder Emerson saw his volley charged down before slicing a drive well wide as the home side finished the first-half on top.
Liverpool came within inches of taking the lead five minutes after the restart. Alonso put Baros through with a sublime diagonal pass and the livewire Czech accelerated past Montero and Thuram before prodding the ball towards goal, only to see his effort roll agonisingly wide.
Emerson's header was safely gathered by Liverpool keeper Jerzy Dudek as Juve mustered their first on-target chance before Djibril Cisse came on for Liverpool for his first outing since breaking his leg in two places last October to complete a remarkable comeback.
The closest Juve came to scoring was when Fabio Cannavaro headed against the post after 78 minutes when Liverpool's Djimi Traore backheaded the ball to him at the far post from a corner.
But the Reds held on valiantly, and with Steven Gerrard to come back and a fully fit Xabi Alonso and Djibril Cisse just weeks away, Liverpool will have no fear when they face Chelsea in the semi-final.
In the night's other quarter-final, PSV Eindhoven sneaked through to the semi-finals with a 4-2 penalty shootout win over French club Olympique Lyon.
Robert hit the winning penalty for the 1988 European champions following a 1-1 draw after extra time that had left the aggregate scores level at 2-2.
It was the first knockout match in Champions League history, apart from the final, to be decided on penalties.
In normal time France striker Sylvain Wiltord gave Lyon a 10th-minute lead. PSV levelled five minutes into the second half with a fierce shot by Brazilian international Alex.
