The goalkeeper made it three clean sheets in as many Premier League games for his new club as the Reds beat Brighton and Hove Albion 1-0 at Anfield on Saturday.
Shutouts in victories over West Ham United and Crystal Palace preceded the game versus the Seagulls, in which he made a vital late reaction save to ensure his team picked up another three points.
That stop from Pascal Gross’ header came after Alisson had displayed ice-cool composure and no little technique by chipping the ball over Anthony Knockaert’s head outside his area to thwart an earlier attack.
