Welcome, then, to 'The Normal One.'

You'll have seen the T-shirts, I presume. Laughed at the memes and the vines. And, I fancy, you'll have allowed your mind to wander into the future, to imagine what could be to come for Liverpool FC .

As introductions go, Jurgen Klopp's at Anfield on Friday was about as impressive as it gets. In message, in tone, in delivery – it was pitch perfect.

If Liverpool's players can channel just some of their new manager's composure, conviction and class into their football over the coming months and years, then the good times will not be far away.

Klopp, though, knows as well as anyone that the real hard work starts now.

He arrives into an unusual situation, eight games into the Premier League season, and with the bulk of his first-team squad away on international duty until the middle of next week. The club captain is injured, as is the £29m summer signing and the most expensive defender in the club's history.

There is no pre-season with which to define and perfect a style of play, no transfer window with which to address the obvious imbalances within his squad. The next two-and-a-half months, then, are about motivating, communicating, organising – while at the same time settling himself into life in a new country, league and culture.

It's a daunting task for anyone, even someone with such obvious charisma and self-belief. Klopp may have been right when he suggested reports of Liverpool's demise this season have been exaggerated in some quarters, but there are problems to be fixed at the club, and not much time to fix them. Expectations are high, and will remain so.

Klopp struck exactly the right note when talking of the need to be respectful to Liverpool's history without carrying at around with them “like a 20kg backpack.” That delicate balancing act, undoubtedly, has proven beyond some in recent years.

It is time for courage, conviction, collectivity – the 'Holy Trinity' of fans, players and manager pulling in the same direction.

Too often, across the past two decades, that has been lacking, with internal politics and individual agendas allowed, criminally, to affect the two things that REALLY matter at a football club – results on the pitch and the happiness of its supporters.

Football is as complicated a sport now as it has ever been, but simple facts remain; a club is infinitely better when all parties are united in their thinking, their ambitions and their willingness to work towards them.

Klopp has already got the buy in of Liverpool's supporters, and will be given time to bring his ideas and philosophies to life at Anfield. We live in age of hype and hysteria, of course, but the response to this appointment has been universal approval and excitement.

He will also, without question, get the buy in of his players, who should be re-energised by the prospect of working under one of world football's genuine elite coaches. If there was confusion and, in some quarters, apathy towards the end of Brendan Rodgers' reign, it will have been washed away this week.

He will demand of them, of course, he will work them tirelessly in order to produce the kind of “full throttle” football he so enjoys.

Good football teams, successful football teams, do not emerge by chance, they require hard work and lots of it. If Liverpool's players want the rewards, they must be ready to give the new man what he wants, day in day out. If they have doubts as to what can be achieved through such work, they need only refer to Klopp's past, both at Mainz and Borussia Dortmund, where he will forever be regarded as a legend.

“It's not so important what people think when you come in,” said Klopp, poignantly, on Friday. “It's what they think when you leave,”

If the rest of the German's Liverpool career is as impressive as his opening salvo, then we are in for some ride.

Brendan Rodgers: Gone but not forgotten

Spare a thought, today, for Brendan Rodgers. From the most talked about man on Merseyside to a mere footnote - his memory, apparently, swept aside by a week’s worth of Kloppomania.

It has been easy to undermine the Ulsterman in recent weeks - and in truth the manner in which some fans have chosen to do so has been unedifying, to say the least. Social media, it seems, brings out the best and the worst in people.

Rodgers will depart, one imagines, consumed by the sadness of what might have been for him at Anfield.

Yet however it ended for him, let us not re-write history. His reign really was a glorious one, for one unforgettable season at least. It would be sad if his time on Merseyside were to be simply airbrushed from the record books. As someone who gave their all throughout his three-and-a-bit years at the club, he deserves respect, if nothing else.
