Do you mean ' City have won 4 of the last 8 Premier League titles'?Absolutely spot on!
Klopp is half decent - no doubt about that, but his previous track record shows he doesn't sustain it.
Guardiola has won 4 of the last 8 Premier League titles and a swag full of other trophies whilst doing it. Mourinho
sustained it for a time as obviously did Ferguson. When Klopp gets somewhere near that we can discuss just how good he is. Let's not forget that he has also spent an absolute fortune (and it has been spent wisely to be fair) doing it, not to mention the sky high wages and agents fees to go with it.
Klopp has done OK but nothing special for the amount of time he has been there. Lets see what he does over the next 2 or 3 seasons? I personally believe he will be gone after next season. Back to Germany for the national job or possibly Bayern.
