An hour gone, Jurgen Klopp had seen enough. He didn’t need a packed midfield to win a game against an Everton team intent on spoiling.
He needed goalscorers. He needed matchwinners. On came Divock Origi, a talisman for Liverpool in this fixture. And Origi changed the game.
In doing so, he may yet change history for two clubs on Merseyside.
Liverpool stay on course for the first quadruple in English football, waiting patiently in case Manchester City falter; Everton, meanwhile, drop into the bottom three for the first time this season just as April prepares to give way to May.
