Although the Liverpool management and Klopp have disagreed from time to time, Klopp has built a competitive team with a limited budget compared to other teams in the EPL. This situation made the Liverpool management happy. In the last years, due to bad transfer policies, things didn't go well and the separation was inevitable.
Whenever I remember Klopp, there will be a bitterness inside me. The seasons missed by 1 point, the Champions League, especially the first Real Madrid final, injuries and incapacities... But we must not forget that Klopp brought Liverpool back from the ashes, brought Liverpool back to the days of the 80s and created one of the best squads in history. In 9 unforgettable seasons he has somehow won everything there is to win. His love and commitment to the city of Liverpool has made him the most loved man on and off the pitch.
It is unlikely that Klopp managed to build such a team with a limited budget, they spent a lot of money, but at some point when the team was formed they only bought or sold several players, so in recent seasons their have been spent in the transfer market were less, than that of Arsenal, which was just forming the team with the arrival of Arteta. By the way, City are also not spending a lot of money on the transfer market now, but initially their spending was very large.
Yes, the Klopp did a very great job in Liverpool, but he was also not an ideal coach, he had good seasons and there were times when the team was going through hard times, but he was constantly with the team, and Klopp is definitely associated with Liverpool, it’s hard to imagine him in to another team.
