• •Tom Allen, Arsenal’s head of sports science and performance, is exiting his role at the club.
• •BBC Sport confirms Allen is the latest departure from the club's backroom staff following a series of recent changes.
• •It remains unclear who will lead the department on an interim basis or what the long-term plan is for restructuring the performance team.

Arsenal’s head of sports science and performance, Tom Allen, is set to leave the club. This departure follows a trend of significant turnover within the club's backroom and executive staff over the last 18 months, including the exits of technical director Edu and several long-term support personnel. While the club has yet to provide a specific reason for Allen's departure, such frequent high-level turnover typically signals a broader shift in internal philosophy under manager Mikel Arteta and sporting director structures. Whether these changes consolidate authority or create tactical instability will likely be judged by the team's physical resilience during the demanding upcoming fixture schedule.
