Dutch midfielder Salah is delighted with his move to Arsenal.
Salah-Eddine has joined Arsenal on a professional contract.
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.
He told arsenal.com: "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 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.
"My first impressions were that not only are my teammates really good footballers, but they're great people as well. The whole environment is positive and it's lovely to work with them."
