Arsenal manager Mikel Arteta has acknowledged the unusual pattern of injuries occurring during pre-match warm-ups, stating it has happened four times this season compared to once or twice in his previous six years at the club.
The most recent case involved Riccardo Calafiori, who was withdrawn before the Wigan game for the second time this season after pulling up in the warm-up, forcing tactical changes including Myles Lewis-Skelly moving to left-back and Bukayo Saka starting in midfield.
