Sorry, but that is not true. Just compare the two situations:
Klopp reached the Final of Europe League and League Cup and the 8th rank in the premier league - yes, he did only train them for the last 30 games, but his points per game was 1,6. That is really, really bad. Second year he had no international games and still only managed 4th place in premier league with 2 points per game. Nobody at Liverpool questioned Klopp. Fa-Cup challenges? I don't think we should talk about that. Still got praise from everybody.
Mourinho won the Europe League and League Cup, reached 6th rank with 1,82 points per game. Not too good, at least Champions League qualification. Second year he failed in the Champions League and managed 2nd place in premier league with 2,13 points per game. Reached the fa cup final and lost. At least half of the fanbase of united questioned Mourinho, a lot of them wanted him to be gone before the season.
Now Klopp is good and Mourinho is losing control. But still Mourinho had on the paper more successful seasons than Klopp in his first 2 years. The difference is that our football was not very entertaining. But i'd still take our 2 seasons instead of yours, even with "shit football". At the end of the season i am not happy with "good, positive, entertaining" football, if we don't win anything. But, unfortunately, i expect Liverpool to win something in the next year(s).
