Ever since Jurgen Klopp arrived at Liverpool back in 2015 it has been a relationship that has grown and blossomed into something the rest of the Premier League would dearly love to replicate.
A manager who genuinely understands a club, a community and fan base, a manager who has built one of the most fearsome teams in European football despite spending less than all of his rivals, and a manager who has delivered a Champions League title and Premier League title.
Klopp's time at Liverpool has been a resounding success thus far, and shows no signs of stopping.
While the date of 2024 and what happens at the end of his current deal remains a concern, for the next three years at least the Reds have one of the greatest coaches of the modern era at the helm.
For Fenway Sports Group, Liverpool's often divisive owners, their greatest success has been bringing in Klopp in the first place.

It was a decision that was planned and one that was done in the belief that the German would be the man to bring success within the model. Ronald Koeman and Carlo Ancelotti, two men who failed to deliver at Everton, were short in the odds, while Ronald De Boer was also in the frame, a manager who would leave Crystal Palace after four games in 2017, all of them defeats.
Klopp was always the standout choice and the man that FSG wanted to replace Brendan Rodgers, who has gone on to show why he was so highly rated since leaving Liverpool, a job that probably came too soon for him.
But while Liverpool have been able to grow and build towards success their rivals have floundered. Manchester United have had Louis van Gaal, Jose Mourinho and Ole Gunnar Solskjaer at the helm while Klopp has been in charge, while Chelsea have had Antonio Conte, Maurizio Sarri, Frank Lampard and now Thomas Tuchel in the dugout.
Arsenal, in their pursuit to remain relevant in the Premier League, have seen Unai Emery and Mikel Arteta come in since Arsene Wenger left in 2018, with only Manchester City's appointment of Pep Guardiola, inked in 2016, standing the test of time.
It has also helped push City on to the next level that they were aiming for, although the Champions League that Klopp won with Liverpool in 2019 still alludes them.
Tottenham Hotspur have tried, like Liverpool, to adopt a business framework behind what they do.
The shiny, state of the art stadium that they moved into in 2019 was a major push from Daniel Levy, one that was supposed to help Spurs generate the kind of revenue that would allow them to keep pace with the biggest in the Premier League.
They flirted with both the Premier League title and Champions League under Mauricio Pochettino, with Liverpool denying them silverware in the latter in the final of 2019.
But after Pochettino was sacked in 2019, just months after leading them to a Champions League final, Spurs have been a club feeling around in the dark for a winning formula, one that has cost them financially.
They are now on the lookout for another new man at the helm after dispensing with the services of Nuno Espirito Santo after a poor start to the campaign, the 3-0 weekend loss to Manchester United the final straw for the Spurs hierarchy.
Sacking Nuno is reported to have cost Spurs just shy of £14m, with the Portuguese, appointed boss in June on a two-year deal, having been earning £7m per year at the Tottenham Hotspur Stadium.

Former Wolverhampton Wanderers boss Nuno was the man chosen to replace Mourinho in the hot seat, with his fellow compatriot having been sacked in April after 17 months in charge.
A pay-off of £16m was due to the current AS Roma boss, who has had three jobs since Klopp has been at Liverpool.
And with sacking Pochettino two years ago having cost Spurs £12.5m, in dispensing with the services of managers they have shelled out £42.5m since Klopp has been at Liverpool, not including what they have had to shell out in wages during that period.
Klopp was hired on a £5m per year deal back in 2015, one that is understood to now stand at around £16m per year. Poor decision making when finding the right candidate has cost Spurs dearly, both financially and competitively.
For FSG, Klopp has been their best call, one that has allowed the club to flourish on and off the field. The headaches that ownership faces with regularity in the Premier League when it comes to changing managers just hasn't been required at Liverpool, a testament to the work of Klopp.
