Fenway weren't there for too long before Klopp arrived. They had a mess to sort out but signings like Coutinho, Suarez, Henderson, Sturridge etc didn't happen with him there. They messed up the Suarez money under Brendan and Carroll was a bad signing, but that's about it. Under Fenway they revitalised a side in mid-table to the point of title challengers, then title and CL winners under Klopp.
I believe they formed a 'transfer committee' and changed their scouting department up post Suarez money splurge too, so they learned from our mistakes. What have we done? Kept the same teams in place despite persistent failures. We've brought in Paratici and the hit rate thus far has hardly improved. It's constant incompetency. Liverpool aren't perfectly run but Fenway have been FAR more successful than ENIC as owners. It isn't even a debate.
