Salah marked his first competitive game under Slot with one goal and one assist.
In a lively performance, the 32-year-old registered four attempts in total, three on target.
Salah is now the outright leader for goals (9) and goal involvements (14 – also 5 assists) on the opening weekend of the Premier League season.
It is only four months since Salah was involved in a very public spat with Jurgen Klopp after Liverpool’s 2-2 draw at West Ham.
“He’s as fit as a fiddle, he’s a real top athlete,” said former England player Joe Cole on TNT Sports.
“He had a different time at the back end of Klopp, but I think he’ll be up there with the goals for sure.”
Salah has looked fresh, sharp and happy in pre-season.
Yet the clock is ticking and the scorer of 18 Premier League goals in 2023-24 is out of contract next summer.
“There are many more years for him to play,” added Slot, who declined to go into detail about Salah’s future.
Salah is one of three key players who could sign a pre-contract agreement with another club in just five months time, with Trent Alexander-Arnold and Virgil van Dijk the other two who are out of contract next summer.
