An hour gone, Jurgen Klopp had seen enough. He didn’t need a packed midfield to win the game against an Everton team intent on spoiling.
He needed goalscorers. He needed matchwinners. On came Divock Origi, on came Luis Diaz. Origi changed the game.
And, in doing so, perhaps the history of two clubs on Merseyside. Liverpool stay on course for the first quadruple in English football; Everton drop into the bottom three for the first time this season just as April prepares to give way to May.
Relegation is no longer a worst-case scenario. It is very plausible indeed.
