Rusty, in a sort of comparison, Mike Brearley captained England with reasonable success, he wasn't really the standard of other cricketers in the team, but was integral to their success.
Henderson is such a player in Klopp's side. His footballing ability is distinctly average though. ( Goals and assists in his Liverpool tenure are poor, even for the Hendo lovers spouting 'He's a holding midfielder')
His passing statistics are seriously embellished as he predominantly passes sidewards or backwards, and only tends to pass to colleagues who are close by and unmarked with rarely no territorial gain or tactical advantage. Klopp obviously encourages this tactic, but as I alluded to previously, Brendan Rodgers wanted shut.
