The fact that Klopp decided to leave the post of coach only causes respect, because he did it himself and moreover understands perfectly well that to sit in the same place, in the same post for a long time will harm not only him, but also the team, because sooner or later the squad will change to such an extent that neither his old nor his new tactics will not work and then the team will start to lose, and the blame will lie on him as the head coach
And I also don't think Liverpool was ready to let him go but he had to do what he did because Klopp is undoubtedly a senior man. I think he left Liverpool to take some rest out of his professional career with whom he's been consistent with for almost a decade now. During his stay at Liverpool, he was able to make laudable achievements including one premier league title and one champions league trophy and these major milestones were a few among other titles and trophies he took home for the club. However before he left, he made sure he set the club's squad depth with some of the young talented players around the world. Mohammed Salah, Van Dijk and Roberto Firminho are just some.of the players to mention amongst them
