Arsenal are reviewing their warm-up procedures after a fourth player suffered a pre-match injury this season, manager Mikel Arteta has confirmed. The most recent case involved Riccardo Calafiori, who was withdrawn before the game against Wigan for the second time this season after pulling up in the warm-up.
Arteta acknowledged the pattern is unusual, stating it happened only once or twice in his six-year tenure at the club before this season. The injuries have forced tactical changes, with Myles Lewis-Skelly moved to left-back and Bukayo Saka starting in midfield for the Wigan match.
