Jurgen Klopp may have received a few critics in recent months, but there is no doubting his calibre as a top-class manager.
After a good but not spectacular playing career, where Klopp primarily featured for Mainz 05, the German was able to forge a terrific managerial career.
After spending seven years at Mainz, he joined Dortmund; where he would stake his claim as one of the best managers in the world.
Dortmund had been struggling for around a decade prior to Klopp's arrival; but he immediately transformed their fortunes.
Within five years, Klopp managed to break Bayern Munich's dominance at the peak of German football, as he led Der BVB to consecutive titles in 2010/2011 and 2011/2012.
He also led Dortmund to their first Champions League final in 16 years, but they were narrowly defeated in all-German clash with Bayern thanks to a last gasp Arjen Robben goal.
Nevertheless, Klopp had proven himself as a world-class manager, and he was soon on the radar of the world's top clubs.
After leaving Dortmund in 2015 following his side's poor run of form, it was Liverpool who won the race for the German's signature.
And the German has already made his mark over here; helping return the Merseyside club to the Champions League in just his second year.
However, it has been revealed that Klopp did dream of managing in the Premier League, but not with Liverpool.
In fact, according to his former boss Eckhard Krautzun, before he made his move to England Klopp is said to have dreamed of managing their bitter rivals, Manchester United.
Speaking to The Set Pieces, per the Liverpool Echo, Krautzen said: "It would be his dream to go to England one day and his favourite club would be United.
"That’s what he said.
"I said (to Ferguson) 'Jurgen Klopp, if he goes abroad, if he goes to England, his love would be Manchester United'.
“I think that’s where his love or respect for Jurgen Klopp grew tremendously."
And Krautzen also added his opinion that Klopp would have got his dream job had the Manchester United role been available when he left Dortmund, but his desire to return to management caused him to take the Liverpool job.
Krautzen said: "After three or four months not working, I knew that he wanted to be in action again.
"When the offer came from Liverpool, I knew he would not hesitate because he wanted to get into a top club in England."
Despite enjoying some success with Liverpool last year, Klopp has not had the best of season's thus far.
His side are currently sit seventh in the Premier League, seven points off top spot, and his side have also stumbled to two draws from their opening two Champions League group games.
Although Liverpool fans will be glad they ended up with the German, he will need to transform the fortunes of his side quickly; otherwise his position come under serious threat.
