Hard to see how Klopp could possibly get more praise than he already gets. The press love affair with Klopp has been well into the pathological for a good while now. The only way he could get more credit is if he were officially named the greatest human being who ever lived.
I would judge a manager by results with respect to what would be the "average" expectation. There are plenty of things to factor in, but if you look across the league and world, basically there is a very high correlation with spending loads of money and doing well. So, Klopp and Pep might be good, great, unbelievable managers, but nevertheless, winning the league is pretty much the expected result when you spend like that. In the case of city, anything but winning a treble is a bit of an under-performance.
The most impressive recent performances are when the results are way, way above what they should be. Like Ranieri winning the Prem (for which he wasn't giving the kind of god treatment Klopp gets for finishing in the top 4 with a vastly more expensive squad), or Moany winning the CL with Porto (for which he gave himself the god treatment)
I guess Klopp isn't on your Christmas gift list. I like the guy. He has some character too him. Same with Mourinho, they add some entertainment value.
