Salah, who could become the club’s most expensive player after add-ons, has featured across four pre-season matches ahead of the forthcoming season.
In those appearances, he’s registered three goals with his latest coming against Hertha Berlin on Saturday, and this coupled with his performances is enough to convince Wijnaldum he’s settled well into his new environment.
“He’s really flying. I didn’t see his goal [against Hertha] because I was in the changing room but I heard it was a good goal,” he told the club’s official website.
“He has settled in really well. He’s not only a great player but also a great person, and that makes it easier for him but also for us to accept him.
“Since the moment he came here, he felt free to be himself. It’s a good thing for us.”
Salah nearly joined the Merseyside club in 2014 from Swiss outfit FC Basel but instead opted for rivals Chelsea, where he struggled to cement himself as a regular presence in the Blues starting line-up having only made 19 appearances.
He would subsequently relocate to Serie A giants Roma, initially on loan, where he reinvigorated his career, in the process attracting attention from a plethora of clubs – notably the Reds.

Capable of playing across the forward line, Salah who is nominally a left winger, helped the Giallorossi finish runners-up to perennial Italian champions Juventus in the season just gone.
His campaign ended with him registering 19 goals and 15 assists in 41 matches across all competitions, with 15 of those strikes coming in the league alone.
