Arsenal have confirmed the signing of Salah-Eddine, after the midfielder left Feyenoord as a free agent.
The deal follows the arrivals of fellow youngsters Tim Akinola, George Lewis and Jonathan Dinzeyi in recent weeks, as the Gunners look to strengthen their youth ranks.
In a statement on the official club website, Arsenal wrote: "Known as ‘Salah’, the 17 year-old has joined us from Eredivisie side Feyenoord as a free agent.
"He will join up with our Professional Development Phase ahead of the new season.
"The Dutch midfielder is renowned for his agility and creativity in the middle of the park. Predominantly a central midfielder, Salah has spent his youth career in the Netherlands, developing through the youth ranks in Rotterdam with Feyenoord.
"We all welcome Salah to Arsenal and look forward to watching his development with us.
"The deal is subject to the completion of regulatory processes."
Speaking to Arsenal digital, the teenager said: "It feels great to join a massive club like Arsenal.
"It’s a good environment for me to work on my development and hopefully through the academy I can become a first-team player.
"They [Arsenal] first contacted my dad and then I went there for a week just to see what the club is all about, and after that they didn’t really have to say anything.
"I immediately knew that it was the right club for me."
Gunners supporters took to Twitter after the deal was confirmed to respond.
One wrote: "Not the player we are waiting for but regardless he is now the best football player with the Surname Salah."
Another tweeted: "Now we can finally say that Mo Salah isn‘t even the best Salah in the country."
