That's according to French football expert Julien Laurens.
"I believe he is yes, he is in the mould of Varane," Laurens told ESPN FC.
"They've got a lot of similarities actually, not just the youth and how they burst onto the scenes in France with their respective club - Lens obviously for Varane around 10 years ago or so and Saint-Etienne with Saliba now.
"But yeah I think there is certainly a path that Saliba will want to follow.
"I think it was the right thing to do for him and for Arsenal as well to leave him another year in France on loan at Saint-Etienne for him then to come back this summer to England and to Arsenal, having gained a lot of maturity from his season in Ligue 1, especially with the injury he had.
"He had to come back and work really hard to come back to his level so I think that will help him a lot and also because this year was very much a transition year for Arsenal.
"Not that he knew that last summer but it became a transition year with Arteta.
"So I think he will be very good for Arsenal coming into the summer, even if he's still very young.
"I think he will be a very good signing."
