He's come from further back than Mourinho, kept Liverpool stable and got them to a Champions League final kicking out a team we're supposed to believe are untouchable, showing progression with every season and are currently very much in the title race. He also got them to an Europa League final which he was as unlucky not to win as we were lucky to win. All while playing a way more entertaining brand of football.
Why shouldn't I mention Klopp and Liverpool?
First he didn't came from "further back" than us. Have you watched LVG's last season or actually tried to put the 2 squads in front of you to compare ? Both were very nearly at the same problems. The squad LVG left had 2 new youngsters as its best players, no at all striker upfront, no proper midfield with Rooney getting shoehorned there to cover that weakness, Smalling as our only reliable defender, no proper fullbacks. It was pretty much a fecked up squad. Liverpool's squad wasn't further back, neither forward too, it was at the same spot regarding the persons imo.
Second, we did good and steady progress under Mourinho in his first 2 seasons, won 2 trophies in his first one, and finished second in his second season while reaching another final. It's only that last summer and the dilemma of Mourinho and Woodward that made us go backward again.
Comparing what both did, I absolutely find nothing to suggest that Klopp did more progress when it comes to results than what Mourinho did, again according to results and results only.
Klopp : Finished 8th, 4th, 4th, lost 3 finals, overall won nothing.
Mourinho : Finished 6th, 2nd, won 2 finals, lost 1, over all 2 trophies.
Klopp plays better football than Mourinho, we all know that but Mourinho has always been about playing ugly and grinding wins to secure results. In terms of results, he did a very decent job, not great but very decent, especially if you consider the results Klopp achieved are good or acceptable.
If Klopp did exactly the same results he did with Liverpool last 3 seasons here, our fans would be calling for his head and would be asking for a big name to start winning things before we become the new Liverpool or Arsenal, and that our ambitions should be higher than bottling a final and how "the mighty have fallen, getting happy because we lost a CL final and finished 4th ffs" and "when the hell is good football enough for United, we want to win trophies ffs!"..etc. All this would have happened and I ensure you it would have happened. Grass just looks greener on the other side.
Liverpool this season are finally starting to look like a proper team once they sold Coutinho and used the money to splash the cash on defense and GK who were their main problems and the thing that prevented them from challenging for a high league finish or win any thing significant, so you can't keep mentioning as an example of improving what you have..etc. They gave up and decided to spend at the end to achieve results.
