Who has the deepest squad in the Premier League?

A Sky Sports analysis assessing player values, rotation, and substitute impact ranked Arsenal top of the Premier League in both the Overall Squad Depth Index and Competitive Depth Index. Following the summer additions of Bruno Guimaraes and Ezri Konsa, Mikel Arteta's side features an average substitute bench value of £367m, retaining approximately 92 percent of their first-team value across an alternative XI.

The study also examined vulnerabilities and rotation habits across other clubs. Manchester United, managed by Michael Carrick, rely heavily on their starting core, which accounts for over 88 percent of their league minutes. Meanwhile, Tottenham under Roberto De Zerbi have rotated heavily, and Aston Villa rank highest in raw squad balance following significant squad turnover.
