Who has the deepest squad in the Premier League?

A Sky Sports analysis evaluating player values, rotation, and substitute impact ranked Arsenal top of the Premier League in both the Overall Squad Depth Index and Competitive Depth Index. Mikel Arteta's side features an average substitute bench value of £367m, retaining roughly 92 percent of their starting XI's market value when fielding a modeled second team.

The study highlighted variations in squad management, noting that Manchester United's core players accounted for over 88 percent of their minutes under Michael Carrick. Despite Arsenal's strong depth, the analysis pointed out specific positional vulnerabilities across the league, including Arsenal's left-wing depth and Everton's centre-forward options.
