It started, as it so often does with this relentless Liverpool team, by pouncing on a loose ball.
After Sadio Mane was beaten by Victor Lindelof in the air, Luis Diaz reacted quickest to claim possession in the Manchester United half and feed Fabinho, who in turn played it to Thiago Alcantara.
The ball was then knocked wide to Andy Robertson before coming back to Thiago who, retreating towards his own goal, held off Marcus Rashford and played safely to Alisson Becker. After a one-two with Joel Matip, the goalkeeper then passed again to the centre-back, who then found Trent Alexander-Arnold.
