Adrian’s overly casual approach to Gomez’s early second-half back pass saw the ball rebound wide off Patson Daka but it typified a lackadaisical approach for which they were to pay when the unmarked Minamino volleyed home Hwang’s left-wing cross.

The warning was not needed as the unattended Haaland rolled home a simple shot from three yards from another Hwang’s cross.

When the bewilderment finally began to subside, Salah struck a brilliant winner, volleying home Firmino’s knockdown for his 12th goal in 13 Champions League appearances at Anfield.

Mane missed a near-post header from Alexander-Arnold’s corner which would have made the finish less anxious than it was but a first win is in the bag.
