An unlikely quadruple remains very much on for Liverpool after a 3-2 victory against Manchester City in the FA Cup semi-final at Wembley.
The national stadium was bathed in sunshine, resplendent, eagerly anticipating round two of arguably the biggest heavyweight clash in world football right now.
Fair enough, technically round three if you include the Anfield game earlier this season, but it felt like a second leg after last week's exhilarating 2-2 draw at the Etihad Stadium that left City one point ahead of the Reds in the race for the Premier League title.
A relatively innocent declaration from former Liverpool defender Jamie Carragher recently that this is now the biggest rivalry in English football caused uproar from those who remember the days of Manchester United and Arsenal going at it, publicly hating one another, fiery encounters, pizza lobbing. That rivalry admittedly had it all.
This is a rivalry of quality, though. It would be a stretch to say City and Liverpool like each other, but there is a clear mutual respect, which some claim stops it being a proper rivalry.
It is an odd thing to point to when the same people were seemingly disgusted by the scenes at the Wanda Metropolitano on Wednesday as City and Atletico Madrid players did not exactly shake hands after the final whistle.
There was some ill-feeling in Wembley ahead of kick-off, with a section of City fans choosing to make noise during a moment of silence to mark the anniversary of the Hillsborough disaster, which the Manchester club later condemned in a statement.
Purely from a football perspective, this is as good as it gets, possibly in the world. It is the new Real Madrid v Barcelona, and this was the latest chapter, their first meeting at Wembley since the 2019 Community Shield, which City won on penalties.
Of course, no-one particularly wanted to be at Wembley, as nice as it looked. With travel from the north west of England heavily affected by a lack of train services over the Easter weekend, questions were raised as to why both sets of fans were forced to travel to London to play a game that was not even a final, but that is a conversation for another day.
On this day, it was the red of Liverpool that reigned supreme.
A strong start for Klopp's men saw Ibrahima Konate continue his recent goalscoring form, nodding in his third goal for Liverpool in the space of four games from Andy Robertson's outswinging corner.
The freshness of the Reds told in the early stages, with Klopp having rested a number of key players in the week, while City had experienced a tough away trip to Madrid, and Guardiola was forced to make several changes to his usual line-up.
His decision to swap goalkeepers soon came back to bite him as Sadio Mane closed down Zack Steffen. While Ederson had teased Diogo Jota at the Etihad in a similar way, Steffen could not match the Brazilian's calmness and saw himself tackled by Mane to concede a farcical second.
Liverpool's midfield was masterful at Wembley. Fabinho managed to keep City's band of attacking midfielders relatively quiet, even after picking up a first-half yellow card. Thiago was just as mesmeric as he had been at the Etihad, finding or creating space, making full use of the vast pitch, and it was his sumptuous dinked ball out to Mane that led to the third, with the Senegalese smashing home inside Steffen's near post.
Of all three Liverpool midfielders, though, you could argue it was Naby Keita who stood out most.
The Guinea international has struggled for fitness and consistency pretty much ever since he arrived in a big-money move from RB Leipzig in 2018, but picked ahead of captain Jordan Henderson for this huge game, he did not let his manager down.
Keita won possession seven times, more than any other player on the pitch in the 73 minutes he featured, and with the ball during that time, nearly matched Thiago (26) for passes in the opposition half (24).
Last week's league encounter had seen City dominate the first half before Liverpool came back in the second, and it seemed the reverse was happening here, except the Merseysiders made more of their dominance with a three-goal lead at the break.
Guardiola's men started the second half much quicker, and had pulled it back to 3-1 within minutes, with a nice Gabriel Jesus run ending with Jack Grealish firing home, just days after admitting he wanted to score more goals after his £100million move from Aston Villa last year.
This was not the same City as last week though, quite literally given the number of changes, and they rarely looked like troubling their title rivals after that, with Jesus hitting an effort when through on goal straight at fellow countryman Alisson.
The Premier League leaders struggled, with just one shot in the first half and Grealish's goal their first effort on target. Their passing accuracy was also way down from its usual high standards at just 80.5 per cent, playing more long balls and failing to deal with Liverpool's famous press.
Though he did not find the net himself, the impact of Luis Diaz was clear for all to see again. The Colombian seems to be improving alongside Sadio Mane and Mohamed Salah game on game.
He won four fouls as he was a constant thorn in the side of Joao Cancelo, while Mane also carried on the fine form he showed at the Etihad.
The former Southampton man became the first Liverpool player to score twice in an FA Cup semi-final since Robbie Fowler against Aston Villa in 1996, and the first to score a brace for the Reds at Wembley since Steve McManaman in the League Cup final against Bolton Wanderers in 1995.
In typical City fashion, they refused to give up until the end, making things interesting with a second goal back in stoppage time courtesy of Bernardo Silva after fine work from substitute Riyad Mahrez.
This was Liverpool's day, though, and if City struck a blow by staying ahead of the Reds in the league last week, Klopp's men responded with one of their own here as we head towards what promises to be an increasingly fascinating rivalry.
Liverpool fans sang Dua Lipa's 'One Kiss' as they got ready for a long journey back up the motorway, safe in the knowledge that history still beckons this season.
