I'm just glad they didn't go for Ancelotti. We pretty much know that the Italian would steady the ship and leave a well-ordered house behind him.
Klopp should be alright but he carries nothing like the same sense of assurance. He's a gamble. No doubt, he's a well-considered, well-advised gamble but it's the nature of these things to disappoint more often than they delight.
He'll be given time and he'll need bags of it. FSG are to be applauded for showing some ambition, rather than going for the safer pair of hands. Whether the "most knowledgable fans in the world" will be as happy to back FSG's intuition and their latest Messiah's grand scheme when the setbacks come along (and they will), is another story. Unless Klopp can win a cup early into his Liverpool career (this season or next, CoC Cup would probably do) he'll be under pressure from the spoilt brats on the Kop and, by extension, the media that loves to pander to that demographic.
Put it another way, it's shit or bust time for Liverpool.
