Klopp doesn't compare to 'Special One' era José, not even in the same ball park.
José turned up and swept English football off it's feet, charming/trolling to the point of hypnotism, winning back to back leagues, ridiculous unbeaten home record, domestic cups.
Special One era José was basically the arrival of a Master Wizard.
Klopp is a good man manager, but his only real mastery is as a 'fan manager'. What I man by that is that he's skilled at cultivating a 'cult of personality' at the club he manages, and at Liverpool he's found a doting wife of a fanbase, to the point that it could be slightly dangerous for Liverpool if he under-achieves.
As I said above, in LvG's 2 seasons after taking over Moyes' mess, he got top 4 and won the F.A Cup, while being largely criticized by the press and by his own fanbase.
Klopp must get at least one of these this season, and even then, he wouldn't have matched LvG's time at United.
After 50 PL games in charge, he's got a worse record than LvG...
