Do you remember the day that a shocked Thierry Henry grabbed on to Jamie Carragher's leg live on television?
It was 4 October 2015, and Sky Sports' analysis of the drawn Merseyside derby took on an even greater significance when news broke that Liverpool had parted company with Brendan Rodgers. Henry's reaction was to create a moment that went viral, before uttering a somewhat inaudible "wow".
Carragher glared into space, blissfully unaware of the advance from his left; a look of someone who thinks he may have left the gas on after leaving home. Composed responses from the pair followed, both expressing surprise that the Liverpool hierarchy made the move eight games into the season.
After coming so close to winning the Premier League in 2013-14, the Reds regressed in the season that followed. Luis Suárez was sold to Barcelona, while Steven Gerrard was entering his last season with the club. There was no Champions League football at the end of it - and pressure was now mounting on Rodgers.
The name of Jurgen Klopp, not said in hushed tones, was being mentioned as a likely replacement should the Liverpool board dispense with the Co Antrim native. With Klopp now available after leaving Borussia Dortmund, a tenure where he guided the club to successive Bundesliga titles and a Champions League final appearance, the behind-the-scenes moves were gathering pace.
At the same time, Rodgers was still in situ, presiding over a less than impressive start to the 2015-16 season. There may have been shock in the Sky Sports studio on that Sunday evening, but that quickly dissipated with the inevitable news that a quick appointment would be made.
On Thursday, 8 October, Jurgen Klopp was unveiled as the new Liverpool manager. John W Henry had got his man, with the Fenway Sports Group convinced that the German would fit the 'project' at Anfield. Sunday Times journalist, Jonathan Northcroft tweeted: "Klopp is made for Liverpool: the job is about charisma, drive, some mad belief...and making a non-stellar squad more than sum of its parts".
Northcroft was prescient in writing such words and there is no doubt that Klopp did bring a charisma to his role, well he's not called 'Mr Charisma' for nothing. On the day of his unveiling at Anfield, he dubbed himself 'The Normal One', the flip of José Mourinho's 'The Special One' assessment. The journalists in attendance would chuckle; they too would also be part of the rollercoaster ride that followed.
Klopp admitted he was "on fire" from the moment Liverpool made their first approach, this while still on a break from football after quitting Dortmund.
The fist pumps, memorably seen during his farewell to the latter, found even greater expression at Anfield.
From early on he was becoming a fan favourite on the red half of Merseyside; the passion and the exuberance on the sideline, while annoying the likes of Sam Allardyce and Alan Pardew early on, only adding to a new-found belief that started to reverberate around a club, who in 2015 were then a quarter of a century without a league title. Foremost in Klopp's in-tray was to end that wait.
Liverpool, let's be honest about it, were in need of a boost upon Klopp's arrival, this in spite of Rodgers coming so close to landing the prize the club were desperate for. Prior to that, Rafael Benitez's side pushed Manchester United all the way in the 2008-09 season, with the Spaniard also famously masterminding that unforgettable night in Istanbul.
The Roy Hodgson tenure was short-lived; a respected manager, but the fit wasn't right. The call to bring back 'King Kenny' was loud. He returned, leading his beloved Reds to two cup finals in the 2011-12 campaign, with the League Cup adding to the club's trophy haul. It was never going to be a long-term stay for the Scot.
The Rodgers era certainly had its moments and who knows what would have happened if he had delivered that Premier League title.
The now Celtic boss did, however, bring James Milner, Roberto Firmino, Philippe Coutinho and Joe Gomez to the club, players that would be key in the era that would follow under his successor.
A 4-1 win over Manchester City in November 2015 was the first indication of what Liverpool, at their best, could do to the opposition when hunting in packs and counterattacking at speed. That said, it was still early doors for Klopp. Come the end of the season, Liverpool finished eight in the Premier League but did get to a League Cup final and Europa League final, losing to Manchester City and Sevilla respectively.
A return to the Champions League was achieved at the end of the 2016-17 campaign, with goals from Sadio Mané, bought from Southampton, no doubt helping them in that pursuit. Klopp was putting the pieces of his Anfield jigsaw together. Mo Salah, who was not terribly loved by José Mourinho during his time at Chelsea, was then purchased from Roma. Along with Mané and Firmino, it would be an attacking trio that would put the coup de grâce on Klopp's full-throttle football.
At the other end of the pitch, though, Liverpool would often have the jitters. In January 2018, Virgil van Dijk arrived to help shore things up, his £75m capture paid for with a bit of change following Philippe Coutinho's £105m move to Barcelona.
A rocking night in Anfield in April 2018 saw Roma cast aside in the first leg of the Champions League semi-final. Enough done to secure a place in the decider against Real Madrid. Hopes were high heading to Kyiv. An evening to forget as Salah went off injured early and Loris Karius lost all confidence between the sticks. Another final defeat for Klopp. A worrying trend emerging!
A new No 1 keeper was required. The club got one of the best in signing Alisson Becker from Roma. Another piece added and with Andy Robertson and Trent Alexander-Arnold continuing to catch the eye, the dawn of another campaign only heightened the expectation that Klopp's Liverpool would finally deliver silverware.
They pushed City all the way in the league, falling just a point short. Their Champions League run looked destined to end at the semi-final stage, with Barcelona holding a 3-0 first-leg advantage. Without Salah and Firmino, hopes weren't high that they could turn it around at Anfield. But they did.
"An Anfield miracle transcribed from the pages of pure fantasy," was the headline of the match report from The Independent.
A rampaging Liverpool tore into Barca from the start, not allowing the Spanish side to breathe. Quick thinking at the corner stick by Alexander-Arnold set up Divock Origi for the decisive fourth goal.
"With 79 minutes gone, the most celebrated team of the modern age had been reduced to bunch of mooching, stumbling yellow-shirted spectators," Barney Ronay wrote in The Guardian.
Onwards to the final and this time Klopp's Liverpool would finally deliver silverware. That's what it was all about on a night Tottenham were defeated 2-0 in a drab encounter in Madrid.
Win one trophy and soon a couple more come along in the shape of the UEFA Super Cup and the Club World Cup. No mad celebrations though, with Liverpool building up a healthy lead in the Premier League.
In the end the club's first top-tier title in 30 years turned out to be a procession. At one stage, they led the field by 25 points. It was all wrapped up with seven games to go in a season where the outbreak of Covid saw the league suspended for three months. A title guaranteed in June, with the trophy handed out at a virtually empty Anfield on 22 July.
For Klopp, it would be the only Premier League success during his tenure. His rivalry, albeit a rather friendly one with Pep Guardiola, saw him again push the Spaniard and City all the way in the 2021-22 season. Again, they fell a point short, with the German overseeing another thrilling ride for the fans in their pursuit of four trophies. They would end up with the FA Cup and League Cup, not the two they really wanted.
The following season Liverpool struggled somewhat as they missed out on a Champions League place.
Ahead of what is now his final season on Merseyside, Klopp did bolster his midfield with the signings of Alexis Mac Allister and Dominik Szoboszlai - part of the German's 'reloading'.
Liverpool were back on it again, though often having to come from behind to win games. Injuries to key players did threaten to upset the rhythm, but academy graduates stepped up with aplomb, particularly in the weeks after Klopp's announced his decision to leave.
Another League Cup was won quite dramatically at the end of February. Another quadruple charge?
With the foot on Manchester United's neck in that FA Cup quarter-final, Liverpool failed to press harder and were undone at the death. A no-show, not in keeping with a Klopp-managed side, against Atlanta at home would eventually end their Europa League quest. Those at the top end of pitch were now misfiring. Salah's form had dipped and Darwin Nunez was displaying the equivalent of the golfing yips.
Losses to Crystal Palace and Everton ended what was a three-horse race for the title. In truth, you would have to say that City and Arsenal were more in control of the games they played.
And now the end is near and Jurgen Klopp faces the final curtain.
If I were to draw on more lyrics from Frank Sinatra's 'My Way', I'm sure Klopp will no doubt have a few regrets, 'but then again too few to mention'.
He certainly gave it all in his pursuit to bring success to Liverpool. His critics will point that he should have won more, but pushing Manchester City twice in memorable title chases and losing a couple of Champions League finals to a more wily Real Madrid, surely lessens the level of criticism there.
Klopp did bring a bit of colour to all things Premier League and more, this in a world where much of the utterances are bland and banal.
It's true to say that he got Liverpool, a force of nature that made the club relevant again. On the day that he announced his departure, Virgil van Dijk said the decision was "a hard one to take" for the club.
Liverpool are an emotional club, perhaps too emotional, at times. Sunday's finale at Anfield, following the conclusion of the game with Wolves, is sure to tug hard on the emotive strings.
And then Klopp will walk away. No more fun on the rollercoaster ride.
Thoughts will quickly turn to next season. The German's presence and abundant energy will be a hard act to follow.
Over to you, Arne Slot.
