As Jurgen Klopp sat in front of a tremendously busy media room when he was being presented as Liverpool's new manager in October 2015, he said his mission was to "turn doubters into believers."
He felt Reds fans were a little too used to coming so near yet so far, having not won a league title since 1990 at the time, and only winning one trophy - the 2012 League Cup - since 2006.
Early on in his reign, after his new team had fallen 2-1 behind to Crystal Palace at Anfield, he was aghast at fans leaving the ground with almost 10 minutes to go, saying he felt "pretty alone" in that moment.
Fast-forward to April 2022, and having won the Champions League, the Premier League, a UEFA Super Cup, a FIFA Club World Cup and an EFL Cup since, it is safe to say that the Liverpool fans are now believers as they sang Klopp's name at the top of their lungs during the 2-0 Champions League semi-final first leg victory against Villarreal.
The Reds are still in with a shout of winning an unprecedented quadruple this season having already won the EFL Cup, with an FA Cup final against Chelsea to come, a lead in their Champions League semi, and sitting just a point behind leaders Manchester City in the Premier League title race with five games left.
News that Klopp had signed a two-year extension to his Anfield deal on Thursday, meaning his contract now runs until 2026, came as a huge boost to fans ahead of what promises to be an exciting run-in, and Stats Perform has taken a look at some of the important steps that took those doubters and filled them with such belief.
Darkest before the dawn
There was a lot to clear up in the squad left behind by the outgoing Brendan Rodgers. If you look at the team Klopp chose for his first game in charge against Tottenham at White Hart Lane, you will see names on the bench such as Jerome Sinclair, Joao Teixeira and Conor Randall, names not too familiar to many now.
"There were many full-throttle moments in the game. We need to improve but after working with the players for three days I am completely satisfied," Klopp said after the 0-0 draw, but he knew he had his work cut out.
Although ultimately it was a disappointing league campaign in 2015-16 for Liverpool, finishing eighth with just 60 points, behind both Southampton and West Ham, Klopp did manage to reach two finals, in the EFL Cup and the Europa League.
He ended up losing both of them, on penalties to Man City and 3-1 to Sevilla respectively. The players were despondent, but as detailed earlier this week by Reds captain Jordan Henderson, Klopp insisted his players not mope, but celebrate what they had achieved, and what he was sure was still to come.
First step in the evolution
After adding Sadio Mane and Georginio Wijnaldum prior to his first full season in charge, many people were a bit underwhelmed, but those fears were soon allayed as Liverpool set about playing the sort of football they have since become synonymous with.
A 4-3 win at Arsenal on the opening day of the season set the tempo, albeit that was tempered by a 2-0 defeat at Burnley straight after in which Liverpool could do nothing with their 80 per cent possession at Turf Moor.
However, as the season progressed, Klopp was able to get a tune out of a potent front three of Mane, Roberto Firmino and Philippe Coutinho, with Mane and Coutinho scoring 13 Premier League goals each, while Firmino added 11 more.
A 3-0 win against Middlesbrough at Anfield on the final day of the season sealed a Champions League spot, but the question was, could Liverpool stay competitive in the league while also navigating through a European campaign?
No player is bigger than the club
Liverpool had made an addition to their already potent attack by bringing in Mohamed Salah from Roma, but the 2017-18 season looked to be thrown into turmoil before it had begun, with Coutinho handing in a transfer request the day before the opener at Watford.
The Brazilian was forced to stay until the January transfer window before being allowed to move to Barcelona, but it did not exactly slow Klopp's men down, largely thanks to the revelation that was Salah.
The Egyptian plundered 4e goals in all competitions in his debut season with the Reds, and coupled with the addition of Virgil van Dijk in January, led to Liverpool making it all the way to the Champions League final in Kyiv.
They were ultimately beaten by Real Madrid thanks to some odd goalkeeping from Loris Karius and a stunner from Gareth Bale, but it felt like the start of something, rather than the end.
Righting wrongs
After adding Alisson and Fabinho to an already strong team, it seemed that Klopp had addressed his two biggest weak points, and so it proved as Liverpool became a near unstoppable force.
They went toe-to-toe with a rampant Man City in the title race, while also showing a determination to avenge their Champions League heartbreak.
They did just that after a remarkable 4-3 aggregate win against Coutinho and Barcelona in the semi-finals, before beating Tottenham 2-0 in Madrid to give Klopp his first trophy at the club, arguably the biggest one of all.
However, in some people's eyes, the biggest one was the Premier League, which they missed out on to City by a single point, despite amassing an incredible 97 themselves. Only City that year and when they achieved 100 the year prior had ever won more points in England's top flight, but it still didn't result in a league title.
Righting wrongs: Part two
Just as they had done in the Champions League, Liverpool had a sense of purpose to go one better in the league in 2019-20, and that led to the title race being over pretty much before it had begun.
A 3-1 win against City at Anfield in the November put the Reds nine points clear of Pep Guardiola's men, and they never looked back, until they were forced to stop their relentless pursuit.
After a break of several weeks following the emergence of the COVID-19 pandemic, Liverpool returned to finish the job and seal their first league title in 30 years after going two points better than the year previous, ending the campaign with 99 to their name.
The beginning of the end?
The pandemic meant every club had lost their fans, with no-one allowed in grounds. While the increasingly believing Kop was missed, it was not until Klopp started losing his defence that problems emerged in 2020-21.
By mid-November, he had lost Van Dijk and Joe Gomez to long-term injury, and Joel Matip completed the set in January, meaning Liverpool had to play a significant chunk of their campaign with either midfielders, or rookie defenders at centre back.
This led to a downturn in results that had people questioning if the ride was over. Had Klopp's relentless Reds finally run out of steam, and was this the inevitable consequence of shining so brightly?
Thanks to some very hard-earned wins, including a remarkable stoppage time winner from Alisson at West Brom, Liverpool scraped third place and a crucial Champions League spot. Had stories of their demise been greatly exaggerated?
The quadruple chasers
Yes, yes they had. With their defenders all back, and Ibrahima Konate added from RB Leipzig, Liverpool have, if anything, found new levels of excellence this season. They have gone right back to challenging City, and have proven themselves to be one of the teams to beat in Europe too.
They are currently the top scorers in the Premier League with 85 goals in 33 games, and have won 13 of their last 14 league games, with a 2-2 draw at City their only blemish in that time.
Can they go all the way and make history by winning a quadruple? It still seems unlikely, but whether they do or they don't, the news that Klopp's story with Liverpool has been extended by two more years can only be positive.
You better believe it.
