On June 1, Jurgen Klopp's four-year project at Liverpool was finally vindicated. 

The German landed his first silverware with the club - and what a way to get off the mark with no less than the Champions League. 

Klopp was suddenly elevated into an elite bracket of Reds bosses alongside Bob Paisley, Joe Fagan, and Rafa Benitez. 

On current form, nobody would bet against the 52-year-old going on to win the Premier League title, Liverpool having made a perfect start to the season with 21 points from seven games.

That prowess is inevitably going to attract wandering eyes from elsewhere, even if Klopp has no immediate intention of leaving Merseyside. 

Inevitably, his stock is particularly high in Germany thanks to his double-winning exploits with Borussia Dortmund. 

And the Daily Mirror report that Liverpool bosses are becoming increasingly concerned at the thought of Klopp taking the biggest job going in his native land - that of the national team. 

Joachim Low remains in charge of Die Mannschaft, but there is a growing feeling that Euro 2020 could be his last major tournament. 

The four-time world champions were arguably the biggest disappointment of last year's World Cup, crashing out at the group stages in Russia. 

Low has tried to oversee a period of transition by axing veterans like Mats Hummels, Thomas Muller, and Jerome Boateng.

If that proves not to be enough and his 13-year tenure comes to an end, the Reds board worry that Klopp - who has also spoken about taking a sabbatical before his next job - could be enticed by the prospect of managing his country.

One way to counter that would be to extend the three years he already has remaining on his contract. 

Perhaps the only consolation would be the possibility of Steven Gerrard's return, which Klopp himself has endorsed. 

"If you ask who should follow me, I'd say Stevie. I help him whenever I can," he said recently, per the Daily Record. 

The same newspaper note that both Kenny Dalglish and Benitez have also talked up Gerrard's chances of moving from Rangers to his old employers. 

In any case, the thought of Klopp's departure at the end of the season remains a daunting one.
