Liverpool have turned the game around with two goals in three minutes.
Scott McTominay gave Manchester United the lead early in the first-half and United looked set to go into the half with a one goal lead.
But Liverpool turned the game around at the stroke of half-time with two quick goals.
Darwin Nunez set up Mac Allister for the first as the Argentine midfielder’s powerful strike took a deflection before hitting the net.
And 3 minutes later, Darwin Nunez was involved again. He cut onto his right before curling in a shot. Onana got a hand to it but it fell straight to Mo Salah who had the easy task of slamming it home from close range.
