The French defender is currently on loan at Marseille and is widely regarded as one of the promising centre-backs in Europe.
He is yet to play his first senior game for the Gunners despite the club signing him three years ago.
Former Arsenal right-back Bacary Sagna has been monitoring Saliba in the Ligue 1 for a while now.
Sagna said: “I’ve watched Saliba this season and his performances have been great for Marseille. He’s been one of the key players defensively, he’s very calm with the ball, he can play out from the back, he’s very strong, good with his challenges.
“I think he just needed some time to play. And Mikel understands that. It’s not that he doesn’t like him, but I think at the age of 18 or 19 you need play, commit to playing every single weekend. He’s not one for staying on the bench, or not wanting to get involved.
“When you are at Arsenal, you need to go somewhere and play and progress, and this is what it is, so I’m looking forward to seeing him back. He’s certainly progressed in France but the Premier League is a different animal. I think he has the ability to succeed and look forward to seeing him back.”
