Arne Slot will struggle to win back fans calling for Xabi Alonso

The speed with which Liverpool folded, even by the standards of a season in which they have had some real lows, was still shocking and left Slot questioning the effort, concentration and fighting spirit of his players.

“If you simply look at the goals, there I see runs that are not being followed, I see crosses that are not being blocked, I see duels in front of goal that are not won,” he said. “Every single time we forget to block a cross, we forget to defend in front of goal, we forget to follow a runner, every single time it’s a goal.”

Luis Enrique, the PSG coach, will pick over this and present a long list of vulnerabilities for his players to exploit and it is not helping Slot that two players who have provided the foundations for so much of Liverpool’s success over the past eight years are struggling so badly. Salah and Virgil van Dijk, to say the least, had nightmare afternoons.

Would this game have turned out differently had Salah not missed the kind of chance in the 15th minute that he would have buried for fun last season? Having got the better of Abdukodir Khusanov from Giorgi Mamardashvili’s long ball upfield, the Egypt striker had just James Trafford to beat but delayed his shot too long and allowed the rapid City defender to make a crucial, last-ditch interception.

The contrast with Haaland was marked. The Norway striker has not had the easiest few months, scoring just five goals in 20 matches coming into this, but his 12th hat-trick for City felt like a marked return to form and will do his confidence the world of good. Stale Solbakken, the Norway coach, took the decision to rest Haaland for the first of his country’s two friendly matches and already the player looks to be benefiting.

Haaland’s emphatic finishing stood in stark comparison to Salah’s total lack of conviction in front of goal, embodied by his penalty miss with Liverpool 4-0 down shortly after ballooning a horrible shot high and wide from another inviting position.
