Overview
- Viktor Gyokeres was absent from Monday’s session at Hale End, making him unlikely to feature in Tuesday’s Champions League trip to Slavia Prague, according to on-site reporters.
 - Mikel Arteta said Gyokeres was withdrawn at half-time at Burnley after “feeling something muscular” and that the club must wait to learn the extent of the issue.
 - Martin Zubimendi participated in training after asking to be substituted at Turf Moor, but he will not play in Prague due to suspension.
 - Injury analyst commentary suggests Gyokeres’ problem profiles as tightness or a Grade 1 strain, with a Grade 1 typically meaning roughly 2–4 weeks out, though scans and club confirmation are pending.
 - Pundits noted Arsenal were less threatening after Gyokeres went off, a concern compounded by other attacking absences as Arteta manages a crowded schedule across the league and Europe.
