Overview
- Mosquera was forced off shortly before half-time after an awkward landing in the 2-0 win over Brentford.
- Early reports point to a six-to-eight week layoff for the 21-year-old, though the club is awaiting tests to confirm the severity.
- Mikel Arteta described the issue as more complicated than first feared and said William Saliba is only days from returning.
- Gabriel Magalhães remains sidelined with a thigh problem that could keep him out until January, cutting into Arsenal’s centre-back depth.
- Jurrien Timber replaced Mosquera against Brentford, leaving Timber and Piero Hincapié among the immediate options for upcoming matches at Aston Villa and Club Brugge.
