Liverpool cruised to a 4-1 victory over Benfica to overturn a first-leg deficit and reach the Europa League semifinals on Thursday.
Fernando Torres scored twice as the five-time European champion wiped out Benfica's 2-1 advantage from last week to advance 5-3 on aggregate.
Liverpool will now travel to Torres' former club Atletico Madrid on April 22 and host the second leg the following Thursday.
Liverpool crashed out of the Champions League, the competition it won in 2005, at the group stage and the Europa League now offers the only chance of ending a four-year trophy drought.
While Benfica is on course to win the Portuguese title, Liverpool is sixth in the English Premier League, four points adrift of the fourth Champions League spot.
Benfica, which was on a 27-game unbeaten run before Thursday, pressed from the start but couldn't extend its aggregate lead.
And just as Liverpool began to gain a foothold, Dirk Kuyt headed the home side in front in the 28th minute after latching onto Steven Gerrard's corner.
The goal was initially ruled out as the referee's assistant on the right flank flagged for offside. But after Torres led Liverpool's protests, referee Bjorn Kuipers reversed the decision and Kuyt was able to end a 1,084-minute goal drought.
Six minutes later, Lucas Leiva gave Liverpool a two-goal cushion after completing a swift counterattack. Having being released by Yossi Benayoun, Gerrard sent a defense-splitting pass through to the advancing Lucas, who rounded goalkeeper Julio Cesar and slotted into the net.
Another lightning-quick break forward saw Liverpool go 4-2 in front on aggregate in the 59th minute. After successfully defending a Benfica free kick, Javier Mascherano dispatched the ball to Benayoun, who raced down the left flank before passing to Kuyt on the right.
The Netherlands forward crossed to Torres, who fired the ball into the net from six meters (yards).
Liverpool looked to be cruising into the last four, but Oscar Cardoza poked a low free kick through the defensive wall to make it 4-3 with 20 minutes to go.
Nerves heightened at Anfield when Cardoza took another free kick shortly afterward, but his shot was deflected wide and Torres netted again in the 82nd.
Mascherano sent Torres through on goal and the Spain striker clipped the ball over Jose Moreira, who had just replaced the injured Julio Cesar.
