Gabriel Withdrawn After Collision; Arsenal Await Fitness Update

Arsenal beat Olympiacos 2–0 in the Champions League with goals from Gabriel Martinelli and Bukayo Saka. Centre-back Gabriel Magalhães was withdrawn after a collision with goalkeeper David Raya and was replaced by Cristhian Mosquera. Mikel Arteta said the substitution was precautionary, expects Gabriel to be “okay” and will make a late fitness decision ahead of Saturday’s Premier League trip to West Ham. Piero Hincapié will be unavailable until after the international break, Noni Madueke is possibly sidelined until mid‑November, and Kai Havertz and Gabriel Jesus remain out as they continue recovering. Arteta highlighted the squad depth that has allowed rotation and praised younger players stepping up.
