The 20-year-old joined the Gunners in 2019 for a reported £27m transfer fee, but he has not played a single minute of first-team football for the club since.
Instead, he has been shipped out on loan to Saint-Etienne, Nice and currently Marseille, establishing himself as a regular member of the first team at each of those clubs.
Saliba's performances this season have been heavily praised, once again raising questions over whether he could have a future at Arsenal, but he insists that he is fully committed to Marseille at the moment.
"I'm on loan. But I pretend I'm there for many years. I'm not thinking about returning to Arsenal [right now]," Saliba told Eurosport.
"I give myself to Marseille. I don't think about what will happen afterwards. Football is like that. In big teams, there is competition everywhere. if you're afraid of the competition, don't play football.
"There are hard times. I hadn't played a game for six months. You have to fight in a career. We must take that as a lesson to go further. It gave me a little slap to say: 'You are nobody!' You can be bought for €30m, arrive in a club and we put you aside.
"I took this experience by being positive. I feed on it. I know what it's like not to play for six months. Today, I want to play every game. It puts the ideas back in place.
"Before arriving at Arsenal, I said to myself: 'Who am I going to play with?' And then you are not even in the group in the Premier League. It gives you a good slap, it feels good. It brings you back to the reality."
Saliba has made 22 appearances for Marseille so far this term, including starting 16 of their 17 Ligue 1 games. body check tags ::
