The Premier League’s summer transfer market shattered records, with clubs collectively spending a staggering £3.4 billion. Yet raw expenditure tells only part of the story.
To gauge how intelligently teams bought and sold players, we adjusted the publicly listed Transfermarkt valuations to reflect the inflationary pressure that lifted fees across the board. By applying a median uplift of 36 percent to those baseline values, we could compare the actual cash outlays with a more realistic market benchmark. This method allowed us to identify which clubs secured bargains, which over‑paid, and which managed to extract the most value when letting players go.
Aston Villa emerged as the surprise champions of the buying side. Despite a summer marked by high‑profile departures, the Villans’ incoming transfers collectively exceeded their adjusted market worth by roughly £60 million. The headline bargain was midfielder Johan Manzambi, whose transfer from Freiburg was priced at £47 million even though our inflation‑adjusted estimate placed his value at £74.8 million. Other astute acquisitions included free‑signing Leon Goretzka, whose contract expiration at Bayern Munich left him on the market with an adjusted value of £13.8 million, as well as Joao Gomes, Matteo Ruggeri and Zion Suzuki, all secured for fees well below their revised valuations.
Arsenal claimed the second‑best buyer slot. Their quest for a marquee striker may have fallen short, but the Gunners still managed to add assets worth more than they paid for.
The most notable deal was the purchase of Piero Hincapie from Bayer Leverkusen for £34.5 million; our model assigned him an adjusted value of £57.5 million, making him one of the window’s most cost‑effective signings. Additional arrivals—Christos Tzolis, Bruno Guimaraes and free‑transfer goalkeeper Illan Meslier—also carried adjusted values that outstripped their fees, delivering a cumulative surplus of £46.6 million for Arsenal.
Chelsea rounded out the top three buying clubs. Their incoming roster was valued at £38.3 million above the total amount spent.
A large portion of that surplus derived from the acquisition of Valentin Barco, who moved from Strasbourg for £34 million against an adjusted valuation of £46 million. Surprisingly, even the £117 million outlay for Morgan Rogers proved a good deal when measured against his adjusted worth of £126.6 million, countering the narrative that the Blues had overspent.
On the opposite end of the spectrum, Newcastle United proved the least efficient purchasers. Our analysis revealed that they overpaid for Aladji Bamba—£35.5 million paid versus an adjusted value that was £14.8 million lower—as well as for Matias Fernandez Pardo, whose fee also exceeded his revised market estimate. Liverpool followed as the second‑worst buyer, primarily because of the steep prices paid for Bradley Barcola and goalkeeper Lucca Brughmans, whose fees overshot their adjusted values by £19.4 million and £25.4 million respectively.
Tottenham Hotspur occupied a curious middle ground. They secured both the best‑value and worst‑value signings of the summer. Free‑transfer midfielder Marcos Senesi arrived from Bournemouth with an adjusted value of £28.8 million, matching Leeds United’s Harry Wilson for the highest‑value free deal. Conversely, Spurs splurged £85 million on Savio, a fee that ran £44.7 million above his adjusted worth, a misstep that was only partially offset by their other purchases.
When it came to selling players, the picture was even more polarized. Only Manchester City and Brentford managed to post positive efficiency scores, meaning they recouped more than the adjusted market values of the players they let go. Manchester City topped the sellers’ list, extracting roughly £1 million above the revised valuations of their departures. Their most lucrative sale was the £85 million transfer of Savio to Tottenham, which exceeded his adjusted value by the same £44.7 million that had previously been a cost overrun for Spurs.
James Trafford’s £40 million move to Leeds also generated an £11.2 million surplus. Brentford’s exit strategy was essentially break‑even, finishing just £0.03 million above the collective adjusted value of the squad members they sold. Chelsea placed third among sellers, albeit with a modest shortfall of £0.5 million. Their standout transaction was the sale of Liam Delap to Nottingham Forest for £17.8 million above his adjusted value, while the £125 million transfer of Enzo Fernandez to Manchester City added another £9.9 million in surplus.
However, Chelsea also off‑loaded defenders Trevoh Chalobah and Marc Cucurella for £15.2 million and £17.2 million less than their revised market worth, tempering the overall gain. Liverpool suffered the harshest outcome on the selling side. The club’s incoming fees fell short by £95.9 million relative to the adjusted values of the departing players. Key contributors to this deficit were the free transfer of Ibrahima Konaté—adjusted at £51.8 million—and the loss of Andrew Robertson, valued at £8.1 million.
Even the fees received for Mohamed Salah and Curtis Jones were well below their revised market estimates. Spurs also struggled in the sales department, ending up £62 million under the adjusted market value of the players they released.
Their departures included Cristian Romero, Luka Vuskovic and Djed Spence, who left for sums £23.5 million, £19.0 million and £16.0 million below their respective valuations. Combining both acquisition and disposal efficiency, Chelsea emerged as the most effective club overall, achieving a net efficiency score of £37.7 million. Their summer was not without hiccups—a failed deadline‑day bid for Lamine Camara—but the aggregate gain still placed them ahead of Aston Villa (£27.1 million) and Crystal Palace (£23.1 million). At the other extreme, Liverpool recorded the lowest overall efficiency at –£136.6 million, trailing behind Tottenham (–£81.3 million) and Newcastle (–£70.8 million).
