William Saliba has been earning rave reviews for his start to life at Arsenal but ex- Manchester United star Roy Keane insists he still "has a mistake in him".
The young France international has been integrated into the Gunners first-team set-up this term after three years spent largely out on loan, and he has wasted little time in adapting to the rigours of the Premier League. Saliba was handed the man of the match gong on his first game, away at Crystal Palace, and has barely looked back since.
He has started every league game for an Arsenal side that currently sit top of the table, having won eight of their opening nine games. This kind of form has sparked shouts that Mikel Arteta's men could mount a serious title tilt.
