There is only one place to start. To try and begin anywhere else would be risible, given the glorious way Mohamed Salah changed the course of this game.
In the 31 minutes before the ball arrived at Salah’s feet, the action had been humdrum and largely forgettable. Liverpool pressed but Southampton held firm and the indication was that afternoon of mundanity beckoned.
But then, fatally, Dusan Tadic dithered on the edge of his own area. Roberto Firmino picked his pocket, Ragnar Klavan found Gini Wijnaldum and he, in turn, rolled a pass to Salah; 25 yards out, the Egyptian took aim and swept a quite magnificent shot beyond Fraser Forster.
