A guide to each club’s setups, from Chelsea’s multi-headed structure to Brentford’s smooth planning and Manchester United’s muddles

The appointment of Andrea Berta as sporting director in March was greeted with much enthusiasm by Arsenal’s supporters, given his impressive track record in more than a decade at Atlético Madrid,. The Italian, who began his career in finance, has made an instant impression. Known as a shrewd negotiator, the suave and softly spoken 54-year-old masterminded Arsenal’s outlay of more than £250m in the summer that included the arrivals of Viktor Gyökeres, Eberechi Eze and Noni Madueke. Berta takes the lead on recruitment in consultation with Richard Garlick, who was promoted to chief executive in September, the manager, Mikel Arteta, and the co-chair Josh Kroenke. James Ellis, a former scout who then spent two years as head of recruitment, was appointed as technical director in the summer and is tasked with “delivering the club’s long-term player progression strategy”, with a focus on creating a pathway from academy to first team.
