Arsenal are considering signing one or more centre-backs to provide cover after an injury setback involving William Saliba. Multiple reports say Saliba is expected to miss a significant period of time, although he does not require surgery to address the back problem he sustained during the World Cup while playing for France. The club’s plans reportedly include strengthening defensive depth to manage Saliba’s absence, with an emphasis on exploring options for additional centre-backs. One report frames the club’s approach as potentially involving substantial spending on a defensive addition, reflecting the importance of having reliable cover in the position while Saliba recovers. The information available indicates the injury does not involve surgical treatment, but does still lead to a prolonged spell out of action. Overall, the reports converge on the same core points: Saliba’s injury is serious enough to rule him out for an extended run, Arsenal are preparing for his absence by considering centre-back reinforcements, and no surgery is required for the back issue.
