Mohamed Salah scored his 26th goal of the season as Liverpool overturned Tottenham Hotspur's first-leg advantage to ease through their Carabao Cup semi-final and set up a final against Newcastle United at Wembley.
The Egypt attacker has been in sensational form and made no mistake from the penalty spot at Anfield after Cody Gakpo had opened the scoring in the 34th minute.
Tottenham had a 1-0 lead from the first leg on January 8 courtesy of a late goal from Lucas Bergvall, but Ange Postecoglou's side never got going and failed to register a chance of note until Son Heung-min struck the crossbar with 12 minutes to go.
Shortly before that, Dominik Szoboszlai had made it 3-0 to Arne Slot's side -- 3-1 on aggregate -- after a well-worked move. Virgil van Dijk, who scored the winner in last season's final against Chelsea, then added a fourth with a powerful header in the 81st minute.
Newcastle booked their spot at Wembley on Wednesday as they beat Arsenal 2-0 at St James' Park to secure a 4-0 aggregate win against Mikel Arteta's side. The final will take place at Wembley on Sunday, March 16.
Gregg Evans and Jay Harris analyse the key talking points...
It may still feel a little early for Anfield to start getting excited, but this Liverpool team has the makings of an all-conquering side.
The League Cup is the nearest route to a trophy and Liverpool, as the holders, have made their intentions clear by charging to the final at Wembley on March 16.
History tells us that more time is needed before a season can be fully defined but Slot's team are not letting up in their pursuit of glory.
Six points clear at the top of the Premier League and with a game in hand, Liverpool are in control of their destiny. Already it feels like a case of when they are going to be crowned champions, rather than if.
That they are through to the last 16 of the Champions League is also an impressive achievement given the tough run of fixtures they faced.
This was supposed to be a season of transition but Slot hasn't flinched since moving to Merseyside and his team are pumped-up, playing wonderful attacking football and suffocating opponents through their relentless running.
Curtis Jones was the heartbeat in the middle of the park, but even the fringe players stepped up to make a difference. Conor Bradley returned back to top form with an aggressive, powerful display at right-back and Darwin Nunez, a crowd favourite, worked tirelessly to torment the Tottenham backline.
This is a huge week for Tottenham and Ange Postecoglou and they have failed the first test.
As they have struggled with a crippling injury crisis over the last few weeks, the second leg of their Carabao Cup semi-final represented the light at the end of the tunnel. If they could overcome Liverpool and reach the final at Wembley, then all of the pain would have been worth it.
With Micky van de Ven, Cristian Romero, James Maddison and Dominic Solanke back in the starting XI for a potential final against Newcastle, they would have been filled with hope at lifting a trophy for the first time since 2008.
Instead, they have barely three days to lick their wounds from this humbling defeat before they face Aston Villa in an FA Cup fourth-round tie. Liverpool suffocated Spurs and prevented them from gaining any type of grip within the game.
Tottenham's slightly passive approach was understandable in the first half when they were holding onto a lead and considering that Richarlison looked sluggish even before he came off injured just before half-time. However, it will be particularly frustrating for Spurs fans that they failed to threaten Caoimhin Kelleher after Salah's penalty gave Liverpool the lead on aggregate.
Spurs have to switch their focus to the FA Cup and Europa League now. They just have to make sure that this crushing defeat does not completely shatter their already brittle confidence.

There he stood, calm as you like, without a worry in the world.
It was up to Salah to convert what at the time was a crucial penalty, in front of The Kop, to put Liverpool ahead in the tie, and could you have asked for a more clinical spot kick?
Not only did he send Kinsky the wrong way, he also slammed in his kick with such pace and precision that no goalkeeper in the world was keeping it out.
Salah's record from the spot this season is impressive. He's scored eight times and missed just the one against Real Madrid in the Champions League.
His form for Liverpool is also a major reason why the team are competing for the quadruple. At Anfield alone he has scored 12 goals and registered eight assists in just 17 appearances.
Back on the left wing this season and in a rich vein of form.
Gakpo is turning into Liverpool's Mr Reliable, stepping up when it matters with the goals that are supercharging their season.
It didn't take Slot long to recognise that Gakpo's best work is produced when he's cutting in from the left rather than occupying a central role.
Admittedly it was a slow start to the season. The Dutchman failed to score in 12 of the first 13 games he featured in under Slot, but since the back end of October, he's hit top form.
Now with 16 goals in all competitions, he's already equalled last season's tally and crucially for Liverpool, he's popping up when it matters the most.
His opener at Anfield made him the first Liverpool player to score five goals in a single season in the League Cup since Robbie Fowler in 2000-01.
He is also now the competition's top goalscorer and was a key part in Liverpool progressing to the final.
Gregg Evans
Tottenham's biggest problem was their inability to hold onto the ball. When they regained possession, Liverpool forced Djed Spence and Archie Gray to play backwards to the goalkeeper Antonin Kinsky.
With a limited number of passing options, Kinsky would hit the ball long where Virgil van Dijk would inevitably win the aerial duel with Richarlison or Dejan Kulusevski. Spence has been exceptional over the last few weeks, and deservedly won the man of the match award against Brentford on Sunday, but he was guilty of trying to dribble past too many opponents at times on Thursday evening.
Maybe that is why Ange Postecoglou switched him to right wing in the second half where he had a smaller chance of losing the ball in dangerous positions for Spurs but could use his speed to beat Andrew Robertson.
Spurs had limited success on the rare occasions they tried to play the ball forward through midfield too. For example, new signing Kevin Danso surged past Darwin Nunez in the 29th minute and passed the ball to Dejan Kulusevski on the touchline. Kulusevski was crowded out, lost the ball and within 30 seconds Dominik Szoboszlai scored but the flag went up for offside.
Spurs were completely trapped in their own half no matter what they tried. They finally paid the price towards the end of the first half when Yves Bissouma could have made a simple pass to Pape Sarr. It went behind his team-mate, Liverpool recovered the ball and charged into the space behind Tottenham's vacant midfield. Salah's cross dropped to Gakpo who did the damage.
It is no surprise that Sarr and Bissouma were hauled off for Pedro Porro and Lucas Bergvall just 10 minutes into the second half, although they have both struggled with injuries recently and were clearly not 100 per cent.
