Arsenal are reviewing their pre‑match warm‑up routines after four separate injuries before kick‑off this season, manager Mikel Arteta said. He called the pattern "very unusual" and said the club is looking into it.
The most recent case involved Riccardo Calafiori, who was withdrawn before the Wigan game after pulling up in the warm‑up. Earlier, William Saliba was ruled out at Anfield with an ankle injury and Bukayo Saka missed the Leeds trip after a mid‑week rest. The incidents forced lineup changes and altered game plans.
