I'm going to point out that if you had got Klopp when he was available, your fanbase (obviously not just on here, wider social media) would have called for him to be sacked if he did as well as he did in his first three seasons at Liverpool (Fourth place would not have been enough for you guys in the second or third season, which is where Liverpool finished)
There would have been many on here calling him 'Jurgen Flopp' and there would have been stupid threads on here talking about how he was overrated at Dortmund and how Woodward was stupid for appointing him when he had never achieved some arbitrary achievement which more down to circumstance than it is managerial ability. I can imagine it now...
"Oh....he nearly got Dortmund relegated, he's obviously past it as a manager but Woodward is so stupid he can't even see that. He's an moron for even considering Flopp to come here" - Obviously Klopp never got Dortmund almost relegated, but I guarantee you'd see the above type of post on here - completely incorrect and illogical on more than one front.
And please, oh please do not try to deny any of this. This place was highly critical of Jose for not finishing closer to City when you finished second, and widely lampooned him for suggesting it was a good achievement. You know the fanbase would have called for the sacking.
My point is: Your fanbase needs to readjust your goddamn expectations, especially when sackings (if not normally hirings) are mostly down to fan pressure. You need to get over yourselves and understand that nothing is ever guaranteed, and anything good is going to take time. Which means actually being willing to grant that time.
