Brentford's new signings get injured more frequently within their first year compared to new signings at other Premier League clubs.
Data from comprehensive injury analytics platforms like the
Premier Injuries Season Review indicates that Brentford actually maintains an exceptionally strong overall player availability record. The club frequently records a raw squad availability rate near 88.8%, which climbs even higher among established core squad members. This demonstrates that the club's medical, recruitment, and sports science frameworks are highly effective at managing player loads relative to the rest of the top flight. [
