Overview
- Gabriel was taken off after colliding with goalkeeper David Raya during Arsenal’s 2-0 Champions League win over Olympiakos.
- Mikel Arteta said the substitution was precautionary and indicated the defender is expected to be available for the upcoming West Ham match.
- Cristhian Mosquera replaced Gabriel on the night as Arsenal protected a player returning to full rhythm after a long layoff.
- Arsenal still have several absentees, with Noni Madueke, Kai Havertz and Piero Hincapié out, while Martin Ødegaard and Bukayo Saka have recently returned.
- If Gabriel does not pass fit, reports suggest William Saliba could partner Mosquera in central defence against West Ham.
