With injuries, rotation, and a relentless fixture schedule shaping the modern Premier League, the quality available beyond a club's starting XI has never mattered more. Sky Sports has ranked all 20 clubs across a series of metrics — including player values, positional cover, substitute impact, and injury records — to determine who is best prepared for the long haul.

Arsenal set the standard

Arsenal emerge as the clear leaders in both the Overall Squad Depth Index and the Competitive Depth Index. Manager Mikel Arteta used the summer window to reinforce the squad rather than chase headline signings, bringing in Bruno Guimaraes and Ezri Konsa to strengthen a back four and midfield already packed with quality.

The combined market value of Arsenal's named substitutes in Premier League matches this season has averaged £367 million — a figure no other club approaches. Accounting for the 36 percent premium above Transfermarkt valuations that Premier League clubs paid on average this summer, that figure rises to approximately £500 million.

A bench that can change matches

Raw value means little if the options on the bench cannot produce when called upon. Arsenal's current squad have combined for 27 goals and assists from 4,340 substitute minutes since the start of last season, generating an adjusted rate of approximately 0.54 goal involvements per 90 minutes. Only Brighton rank above them for goal involvements per 90 from the bench, though Arsenal lead on raw totals.

Rotation trust and minutes distribution

Possessing depth and actually deploying it are two different things. Manchester United's core XI has accounted for more than 88 percent of their league minutes — a figure surpassed only by Bournemouth and Everton. By contrast, the players ranked 12th to 22nd at Arsenal and Manchester City have each accounted for around 15 percent of their respective sides' minutes.

Tottenham have distributed a comparatively high share of minutes beyond their core XI, possibly reflecting that manager Roberto De Zerbi is still identifying his strongest combination.

The second XI test

Arsenal's modelled first XI carries a market value of £580 million, while their second XI is valued at approximately £536 million — meaning they retain roughly 92 percent of their first team's estimated value even when all 11 starters are replaced. Manchester City, by comparison, suffer a drop of £428.2 million between their first and second XIs, largely due to the enormous gap left by removing Erling Haaland up front.

Both Aston Villa and Hull currently have a second XI valued above their usage-based first XI, a reflection of the late arrivals still integrating under Unai Emery and Sergej Jakirovic respectively.

Positional strengths and weaknesses

Even the deepest squads carry vulnerabilities. Arsenal are short at left-wing following the departures of Gabriel Martinelli and Leandro Trossard. Liverpool face a similar problem on the right flank in the wake of Mohamed Salah's sale. Brighton, Crystal Palace, and Newcastle each rank poorly for attacking midfield depth, though all three regularly play without a recognised number 10.

Everton sit bottom — 20th — for centre-forward depth with a score of 36.1, a situation made worse by the failed attempt to sign Folarin Balogun. That does not reflect poorly on their starting striker Thierno Barry, but rather on the quality of alternatives behind him.

Young players and development value

Chelsea boast the most valuable group of under-21 players in the division, with seven players — including Willian Estevao and Geovany Quenda — worth a combined £229.5 million. Manchester City rank second at £190.9 million, followed by Brighton at £179.1 million, Manchester United at £177.1 million, and Bournemouth at £159.5 million.

Of those five clubs, only Brighton and Manchester United rank in the top five for actual minutes played by young players. Manchester City's under-21 group has played just 257 minutes, while two young Arsenal first-team players worth £72.7 million have accumulated 282 — still considerably more than Leeds United's single minute of action.

The three promoted sides — Hull, Coventry, and Ipswich — have the lowest average bench values in the division, while Brentford stand out among the traditionally smaller clubs with an average bench value of £129 million.
