When Jurgen Klopp arrived at Liverpool in October 2015, with his blonde hair and huge smile, he dubbed himself the 'Normal One'.
It was in stark contrast to Jose Mourinho's arrival, of course, with the Portuguese dubbing himself the 'Special One' when he first touched down at Chelsea all the way back in 2004.
Except Klopp's time in charge of Liverpool has been anything but normal. He has brought magic to a club that, previously, was lacking characters capable of waving a wand and casting a spell.
Liverpool came close to winning the league under Brendan Rodgers and Rafa Benitez but neither could get the club over the line. It appeared, for 30 years, that one of the country's biggest giants had been struck with a curse from the gods above.

Yet Klopp hasn't just lifted the curse, he has banished it to distant memory. Liverpool are a force, a team with talent coursing through every department. Right now they're the favourites for the Premier League title - while Carabao Cup, FA Cup and Europa League glory isn't out of the question either.
However, dark clouds are now over the city of Liverpool once again. The red side, at least.
Klopp stunned the footballing world on Friday by announcing his departure at the end of the season, having exhausted all of his energy after eight-and-a-half years of remarkable service.
Immediately, fans reacted. Many mourned, expressing sorrow, lamenting the fact that one of Liverpool's greatest managers is heading off into the sunset.
Klopp is set to take a break from football. He wants to spend more time with his family, his friends and to live life away from the harsh and unforgiving spotlight the sport casts over it's biggest and brightest figures.
There has been talk of the Germany job, even Real Madrid or Barcelona, but neither seems feasible right now. Klopp is out - and unsure what the future holds.
But arguably the biggest intrigue surrounding the 56-year-old's imminent exit is what happens to Liverpool next.
When Sir Alex Ferguson retired in 2013, having won 13 Premier League titles at Manchester United, it was a seismic movement in Premier League history.
Suddenly the country's biggest force was vulnerable and weakened. Suddenly, challenging for titles every year was no longer a guarantee, with the landscape changing drastically.
United went with David Moyes, who would last just 10 months after being given a six-year contract.
They have gone through the likes of Louis van Gaal, Jose Mourinho, Ole Gunnar Solskjaer and Erik ten Hag in the years since.
But United are a shadow of the club they used to be. Their malaise has turned into something more. Whisper it quietely, the curse may have been moved on to them now.
People criticise the Red Devils for the money they've spent and rightly so. However, virtually all of their managerial appointments since Ferguson's retirement have been wrong.
Moyes had no experience of winning when he took charge of a dressing room full of champions. He was always going to be eaten alive.
Van Gaal was past his best, while the same could be said for Mourinho - even if the trio won three trophies between them.

Solskjaer wasn't qualified for the job either, while Ten Hag has found managing United completely different to being in charge of Ajax.
Liverpool, simply put, can't afford to fall into the same trap.
Klopp is a hard act to follow. His charisma, his tactical nous, his canniness in the transfer market and his ability to improve players all make him one of the best managers in Premier League history.
There is no obvious successor as a result. Some might disagree, however.
The common consensus is that Xabi Alonso is the frontrunner to take charge, having done an excellent job at Bayer Leverkusen so far.

Alonso knows Liverpool inside out, having spent five years at the club between 2004 and 2009 before leaving for Real Madrid.
He would, however, still represent a gamble given he's only been managing for a few years.
Steven Gerrard has been linked but only a fool would go for the former Liverpool captain now. Given how the Reds operate these days, the chances of him returning to Anfield seem less than remote.
Zinedine Zidane is a serial winner from his spell at Real Madrid but managing in England doesn't seem to be on his agenda.
And while Roberto De Zerbi is in demand, he's happy at Brighton and eager to see out his project at the Amex Stadium.

Klopp deserves his time away.
But Liverpool need to get their successor right. If not, becoming the new Manchester United might just happen.
