In a Premier League campaign that is increasingly dictated by injury crises, squad rotation and a jam‑packed fixture list, the ability of a team to cope when its first‑choice eleven are unavailable has become a decisive factor. Understanding how much quality lies beyond each club's established starting line‑up, how much of that quality is retained when starters are swapped out, and where the strengths and weaknesses of each squad lie is essential for gauging a team's resilience over a long season.
To answer these questions we built a comprehensive Squad Depth Index that takes into account a range of variables: the drop‑off in quality from the first XI to the second XI, the overall calibre of reserve players, positional coverage, actual rotation patterns, and the readiness of each individual to step in at short notice. In addition, we created a Competitive Depth Index that layers in the expected performance standard for each club (derived from Sky Sports' forecasting engine), the total market value of the squad (sourced from Transfermarkt), and the upcoming fixture congestion and injury history. By merging these data streams we can compare how well each club’s bench matches the demands of the season ahead. The results are clear: Arsenal sit at the summit of both the Overall Squad Depth Index and the Competitive Depth Index.
While not a shocking outcome given the resources Mikel Arteta has marshalled, it does raise the question of what exactly makes the Gunners' squad so deep and dependable compared with the rest of the English top flight. Our methodology began with Sky Sports combining Opta playing‑time statistics and match data with Transfermarkt’s estimated market values. This allowed us to identify each club’s regular starting XI and the strongest alternatives available. We then measured how much quality is retained when a starter is replaced, the overall reserve quality, positional cover, the frequency of actual rotation, and player readiness.
For attacking substitutes we examined their impact in the Premier League over the previous two full seasons plus the current campaign, adjusting the rates for sample size to avoid skew from one‑off appearances. The Competitive Depth component also factored in the standard each club is expected to maintain (based on Sky Sports’ super‑computer forecast) and the total squad value. Arsenal’s summer transfer activity illustrates their strategic focus on depth.
Although the club flirted with marquee targets such as Vinícius Júnior and Julián Álvarez, the acquisitions of Bruno Guimarães and Ezri Konsa have already added quality to a back four and midfield already brimming with talent. Arteta also had to navigate a lengthy injury list last season, a situation the club hopes to avoid this time around. When we look at the market value of Arsenal’s named substitutes in Premier League matches this season, the average sits at a staggering £367 million – a figure no other club even approaches. It is worth noting that Transfermarkt valuations tend to be lower than actual transfer fees; Premier League clubs typically pay around 36 % above these estimates.
Applying that premium pushes the effective bench value to roughly £500 million, underscoring just how deep the Gunners’ pool of talent truly is. By contrast, the three promoted clubs – Hull City, Coventry City and Ipswich Town – have the lowest average bench values. Mid‑table side Brentford is an interesting outlier, posting an average bench value of £129 million, which places them just outside the traditional ‘big six’ but still ahead of many established clubs.
Market value alone, however, does not guarantee usefulness. To gauge actual impact we measured every Premier League player’s output when entering a match as a substitute across the past two seasons and the current one. Goals and assists per 90 minutes were normalised toward the league average based on the size of each player’s substitute sample, preventing a single 10‑minute cameo from inflating the rankings. On a per‑90‑minutes basis for goal involvements, Arsenal rank second only to Brighton, and in raw total contributions they sit at the very top.
Since the start of the 2022‑23 season, Arsenal’s substitutes have combined for 27 goals and assists over 4,340 minutes, delivering an adjusted rate of about 0.54 goal involvements per 90 minutes. Depth becomes crucial after the international break, when the Gunners face one of the most demanding schedules in the league. Yet possessing depth is meaningless if a manager does not utilise it.
To assess usage, we ranked every club’s players by total Premier League minutes and split them into three tiers. Tottenham Hotspur, for example, have already allocated a relatively high share of minutes beyond their core eleven, despite competing on fewer fronts – perhaps a sign that Roberto De Zerbi is still experimenting with his strongest lineup. Manchester United’s core eleven command more than 88 % of the team’s minutes, a figure only eclipsed by Bournemouth and Everton. Despite having a squad capable of handling a congested schedule, Michael Carrick has yet to place full confidence in his rotational options.
In comparison, Arsenal and Manchester City have allowed players ranked 12th‑22nd in their squads to account for roughly 15 % of total minutes, indicating a more balanced distribution of playing time. To test how clubs would cope with an extreme injury crisis that wipes out the entire first team, we built a standardised first XI for each club based on current Premier League playing time, then constructed a second XI from the remaining squad. Arsenal’s modelled first XI is valued at £580 million, while the second XI is worth about £536 million – a retention rate of roughly 92 % of the estimated value of the starting side even when every starter is replaced. Manchester City, by contrast, sees a drop of £428.2 million between its first and second XI, largely because the value of the squad collapses when Erling Haaland is omitted.
Aston Villa and Hull City are the only clubs whose second XI is actually valued higher than their usage‑based first XI, reflecting aggressive late‑window transfer activity that is still being integrated. Even the deepest squads encounter bottlenecks when a specific position lacks adequate cover.
We broke each squad down into ten distinct roles – goalkeeper, right‑back, centre‑back, left‑back, defensive midfield, central midfield, attacking midfield, left wing, right wing and centre‑forward – and evaluated the two strongest credible options for each (four for centre‑back, where two spots exist). This granular view revealed that Arsenal, despite overall strength, are notably thin on the left wing after the departures of Gabriel Martinelli and Leandro Trossard.
Liverpool’s situation is even more acute on the opposite flank following Mohamed Salah’s exit. The weakest positional depth across the division appears in the attacking midfield slots of Brighton, Crystal Palace and Newcastle, although these clubs often operate without a traditional number 10.
Everton rank 20th for centre‑forward depth, scoring a low 36.1 after a failed pursuit of Folarin Balogun – a sign that while their starter Thierno Barry may be competent, the quality of his alternatives lags behind the league. When looking at overall squad balance, the reigning champions sit among the most well‑rounded sides. Aston Villa edges them only in the pure Squad Depth Score, which measures the strength of alternatives relative to the first team.
Recent departures such as Morgan Rogers, Ollie Watkins, Youri Tielemans, Ezri Konsa and Emi Martínez have narrowed the gap between starters and rotation players, making the squad more cohesive. Youth also plays a pivotal role. Our model includes development players who have either established market value or earned Premier League minutes. Chelsea boast the most valuable cohort of young first‑team players in the league – seven individuals aged 21 or under with a combined worth of £229.5 million, all of whom are home‑grown signings like Willian Estevão and Geovany Quenda.
Manchester City rank second (£190.9 million), followed by Brighton (£179.1 million), Manchester United (£177.1 million) and Bournemouth (£159.5 million). However, value does not always translate into minutes; Brighton and Manchester United are the only two of these five clubs that feature in the top five for total minutes played. Manchester City’s young group has logged a mere 257 minutes, whereas Arsenal’s two promising youngsters worth £72.7 million have combined for 282 minutes – still a far cry from Leeds United’s solitary minute of youth involvement.
Finally, we simulated the removal of each player from every club’s first XI, rebuilding the strongest possible lineup from the remaining squad each time. This stress‑test highlights which positions would suffer the greatest structural damage if a key player were unavailable.
Unsurprisingly, goalkeepers dominate the list, with Brighton’s Bart Verbruggen representing the biggest potential loss in the league. Among outfield players, Aston Villa’s youngster George Hemmings, Bournemouth’s Adrien Truffert and Crystal Palace’s Adam Wharton emerge as the most critical.
Overall, the analysis underscores that while Arsenal currently possess the deepest and most versatile bench in the Premier League, depth is a multifaceted concept involving market value, actual on‑field impact, positional balance, and managerial utilisation. Clubs that can blend these elements effectively will be better equipped to navigate the inevitable injuries, fixture congestion and competitive pressures that define modern top‑flight football.
