Liverpool started the game in energetic fashion as would be expected from a Jurgen Klopp team, and had gone close through Sadio Mane early on.
West Ham had opted to sit deep to absorbe the pressure, but once they regained the ball they pushed forward.
The ball was recovered in the Liverpool half and given to Naby Keita who made a purposeful run forward on the counter.
The new signing passed the ball in to the path of Andy Robertson who was virtually unmarked on the left wing, who perfectly cross the ball in low for Salah to turn it home.
