Arsenal's reluctance to use William Saliba since his £30million Emirates switch has been questioned by former Gunners academy star Stephy Mavididi - now taking France by storm at Montpellier.
Mavididi spent eight years in north London as an Arsenal academy prospect before eventually calling time on his stay with the club to join Juventus, after being scouted by the brother of Giorgio Chiellini.
The striker has since moved on to Ligue 1 where he has come up against Saliba, currently on loan with Marseille.
