If Jurgen Klopp is true to his word, then his third and final act at Liverpool is already underway.

The Reds manager's most recent contract, signed in December 2019, runs until 2024, which will take him up to nine years at Anfield.

It will be the longest the German has ever spent at one club after his two seven-year stints with Mainz and Borussia Dortmund back in his homeland.

And if Klopp is to stay no longer than 2024, then his six-year anniversary as manager this month now sees him entering the last third of his time with Liverpool.

The main theme of Klopp's tenure so far has been one of progress; both steady and spectacular at various junctures.

After a promising opening few months ended in heartache in both the League Cup and Europa League finals, Klopp followed that up by back-to-back top-four finishes, while re-establishing the Reds a continental force with a run to the Champions League showpiece in Kiev.

From there, the charge went into overdrive, with Klopp's men winning the Champions League, Premier League and a first-ever Club World Cup during a halcyon period between June 2019 and July 2020.

If that is to be the heyday of the Klopp tenure, he will walk away after nearly a decade as the most celebrated Liverpool manager of the 21st century.

The late, great Gerard Houllier may have won more silverware than Klopp's current haul, but in the Champions League and Premier League - the first domestic crown in 30 years, no less - there are no bigger prizes in club football.

Add in a maiden Club World Cup, secured in Qatar during that draining mid-season period of December 2019, and it is clear Klopp's Liverpool were the finest on the planet during those trophy-laden months.

But if this reminiscing sounds like reflection at the end of an era, it shouldn't.

As Klopp enters the final three years of his stay on Merseyside, there is a burning desire that is continuing to push him and his staff on to greater heights.

One that is slightly singed by what might have been. Or what could yet be.

"I think we still want to do more and win more, so that drive is still there," one senior source at the club told the ECHO over the international break.

"Jurgen has changed the atmosphere totally as well [since he arrived].

"He changed that all by speaking to the fans and, if you like, he showed them the passion he has brought to the club."

Long-time goalkeeping coach John Achterberg recently revealed how those inside the inner circle talk about repeating their feats of 2020 - in front of their own fans.

He told the Athletic this week: "It’s a shame we didn’t get to do the league how it should have been [because of COVID-19].

"We did the Champions League right. People were going to fly in from all over the world to celebrate. Everything was booked out in Liverpool.

"There were one million on the street when we won the Champions League.

“When you win the Premier League, it could have been double that."

The events of Thursday July 23, 2020, will never be forgotten by anyone associated with this football club, but that just 500 were inside Anfield to see Jordan Henderson hoist the Premier League title aloft surely dimmed the celebrations ever so fractionally.

"We would love to do it again," added Achterberg. "The players, the staff, we talk about this.”

Clearly, then, that desire to share more success with their supporters is something that provides motivation behind the scenes.

That is likely to be the unique inspiration for this Liverpool squad as Premier League hostilities are due to be renewed this weekend.

Could it also be the X Factor that Klopp and his players need to ensure it is their name in first place when the final whistle sounds in May?

It is one element that their rivals simply don't have.
