Piero Hincapie starts the north London derby alongside William Saliba in the heart of the defence.
It’s his first Premier League start after arriving from Bayer Leverkusen in the summer – he’s made two substitute appearances for us in the league so far, though did start our most recent Champions League match, at left back.
He comes in for Gabriel Magalhaes, who picked up an injury during the international break, and so misses his first Premier League game of the season.
Other than that, it’s the same starting XI that drew against Sunderland two weeks ago, but Mikel Arteta is able to welcome back two players from injury among the substitutes.
