William Saliba spent years out in the cold under Mikel Arteta, but now looks set to be a mainstay in their backline.
The French defender has started Arsenal's opening two Premier League games and put in impressive performances in wins over Crystal Palace and Leicester, even if there was an unfortunate own-goal in the latter fixture. Saliba, who previously impressed during loan spells at Nice and Marseille, is quickly making himself undroppable alongside Gabriel.
Arsenal had signed centre-halves in three consecutive summers, with Saliba's acquisition followed by Gabriel and then Benjamin White. Last term, it was the latter two who formed a partnership which proved solid throughout a progressive season for the Gunners.
