That's a strange and perhaps even ridiculous comparison. RDM has no pedigree or track record of success in league terms in any country. Klopp has won multiple titles in arguably the 2nd or 3rd strongest league in Europe dominated by one of Europe's biggest superpowers. RDM had an unbelievably lucky run. Winning the league can't be described as luck. They were only knocked out by Real Madrid (the eventual winners) IIRC the following season also in the knockout stages.
You're the one who suggested that one good run in Europe made Klopp proven.
In his 7 years at the club they made the final once, the quarter finals once and last season the round of 16 where Juventus trashed them.
He won back to back league titles as Bayern were rebuilding their squad and then sacked LVG. He's a good coach, but far from the genius or miracle worker he is portrayed as in the media.
