The snake oil peddler!
Ok lets rewind a bit and remember the facts of the matter. H&G caused untold damage to LFC, Rafa tried to fight a one man defence and will the best intentions in the world, blew it. Hodgson, who rivals Donald Trump as the world's village idiot was appointed when everyone would tell you he was incompatible with the job, club and fans. But at least we didn't get Fat Sam like the blueshite have.
Broughton played a good hand as chairman and brought in FSG.
Woy had to go, Kenny took over as someone rightly said, to restore some sanity and stability to the club. Being out dated it didn't last.
FSG being inexperienced but showing imagination went for a young man. Fans at the time were not upset and Rodgers was appointed.
In the short term the club struggled to regain control of its finances and there were transfer budget constraints so the Moneyball strategy was adopted. At the same time Comolli was brought in to guide FSG and Rodgers and reproduce some of the young talent finds he'd done at Spurs. So Rodgers was a gamble but was supported by Comolli - seems sensible to me.
The team that came second had Suarez, Sturrdige, Sterling, Gerrard, Carra, Henderson, Joe Allen, Migs - it wasn't bad! But Suarez left, Sterling was sold and we went into the doldrums.
What annoyed the fans most was despite the declining standard of footie on the pitch and dropping points and conceding goals, the manager insisted that they were 'amazing', 'outstanding', 'Massive effort' when we could all see it was cr@p. Rodgers lost credibility, Moneyball didn't work and we ground to a halt. The fans and to some extent the players gave up on Rodgers.
So FSG brought in Klopp on the 3rd highest EPL manager's salary to turn it round. He set amongst the slackers, brought in new blood and rejuvenated some of the existing team.
To answer my own question what have they done wrong, I'd say as new owners and not understanding English footie, the fans or the club, they've done remarkably little wrong and what they did do wrong in the first 2-3 years has been repaired.
There's no one out there right now I'd swap them for, thats for sure.
