'Saints' defender Wesley Hoedt had a shakey start to the game, with Mohamed Salah taking full advantage to run in behind the centre-back early on.
When Hoedt failed to cut out a routine ball forward from deep, Southampton were suddenly in a world of toruble.
The Egyptian latched onto the ball and held off long enough to draw Jack Stephens to him before squaring for Firmino to stroke home from just inside the box to open the scoring.
