Liverpool beat RB Leipzig 5-0 on Thursday evening, with new signing Darwin Nunez stealing the show with four second-half goals.
A capacity Red Bull Arena took in the action, as Liverpool fans played their part in what was a raucous atmosphere before kickoff.
The Egyptian finished well with a low strike, before celebrating with the excellent Andy Robertson.
Liverpool led 1-0 at half-time before Klopp began to ring the changes, with Nunez one of four players introduced at the interval.
Luis Diaz was scythed down soon after the restart to earn the Reds a penalty and Salah selflessly gave it to Nunez, who – just about – buried his first (non-competitive) goal for the club.
Skipper Jordan Henderson was clearly delighted for his new teammate…
This was just the start for Nunez, though, who then finished clinically almost straight after to bag his second goal of the night. A nice finish this time, very trademark No.9.
The hat-trick was complete when he found the net with a poached effort from close range, before rounding off the scoring with a strike that squeezed through the Leipzig goalkeeper in the final minute.
After the final whistle, Klopp and Henderson saluted the travelling Reds fans, who were treated to a pre-season exhibition by their heroes.
There was also time for the boss to embrace with new big-money signing Nunez, no doubt breathing a sigh of relief that he has got his goalscoring monkey off his back.
Next up for Liverpool is a clash with Salzburg in Austria next Wednesday (7pm BST).
