His start has been spectacular: seven goals in his first six league appearances, including a hat-trick and an assist against Galatasaray.
Davide Petrucci knows the feeling.
The former Manchester United midfielder spent three seasons with Çaykur Rizespor after leaving CFR Cluj, arriving in Turkey in 2016 and immediately becoming a regular. He made 37 appearances in all competitions in his first season, including 30 starts in the Süper Lig, before experiencing relegation and then helping Rizespor return to the top flight.
It was enough time to understand why Turkish football leaves such an impression on players who experience it.
"In Turkey, I had a great time," he tells Football Presse. "I really enjoyed football there because it's a big country where people love football. They have amazing stadiums and crazy supporters. The fans are really passionate about their football and their clubs.
"When you play in those stadiums with that atmosphere, it's something that stays with you forever. Sometimes you feel the stadium jumping. The whole stadium is jumping and it feels like it's moving. Playing in big stadiums, against big clubs, with 60,000 people — it was incredible."
Petrucci had already experienced the demands of English football at Manchester United and played in Romania before arriving in Rize, but Turkey offered something different. The supporters weren't simply creating noise around the match; their presence became part of the game itself.
"It makes you feel like a football player. That's what I enjoyed about it. When you go there and you play in those stadiums, with that atmosphere, you really feel the passion. I'm happy that I experienced it."
Rizespor were not one of Turkey's giants, but Petrucci still found himself playing against the country's biggest clubs and in environments that could overwhelm visiting teams. His first season included league matches against Galatasaray, Fenerbahçe and Beşiktaş, while the club's supporters gave him an introduction to the intensity that exists well beyond Istanbul.
And there was another side to his Turkish experience: learning what happens when the football doesn't go according to plan.
Rizespor were relegated at the end of Petrucci's first season, but the midfielder remained as the club moved into the second tier. They returned to the Süper Lig, and Petrucci was back playing against the country's biggest sides. By the time he left, Turkey had become one of the defining experiences of his career.
"When I was there, not many players had played in Turkey, but after some of us went there, people started following it more. Now, every year, more players go. I think Italian football is also followed there because there are so many good players and coaches."
That evolution makes Salah's decision to move to Trabzonspor particularly interesting. He doesn't arrive as a player looking for a route into European football. He arrives after years at Liverpool, having won the Premier League and Champions League and established himself as one of the game's biggest stars.
Yet the attraction of Turkish football isn't necessarily about what a player needs to achieve professionally. It is what the experience gives back to him.
"When you play there, the atmosphere is great. The stadiums, the fans, the clubs — there are big clubs and incredible support. If a player has the opportunity to experience it, I would advise them to try it."
Petrucci believes the appeal is impossible to fully understand until you are standing on the pitch yourself.
"You feel the stadium sometimes jumping. The whole stadium is moving. When you play in front of 60,000 people like that, it makes you feel like a football player."
That is perhaps why his memories of Turkey remain so vivid despite the twists and turns of his career. He played in England, Romania, Turkey, Israel and Italy, but his time in Rize gave him something that statistics cannot capture.
The stadium was alive.
"The fans are really crazy for football and for the clubs. So when you go there and you play in these stadiums with this atmosphere, it's something that stays with you forever."
Salah is now finding out for himself. His early months at Trabzonspor have already included the kind of occasion Petrucci remembers: a packed stadium, a major opponent and a performance that turns the player into the centre of an entire football city's attention.
For Petrucci, that is what Turkish football does particularly well.
"I would advise everybody to go because when you play there, the atmosphere is great. The stadiums, the fans, the clubs, the big clubs — it's something a player should experience."
And after three years living it rather than simply visiting it, Petrucci knows exactly why.
"It makes you feel like a football player."
