Do Transfer Fees Actually Predict Success? Soccer

Excluding the Deals That Haven't Had Time to Prove Anything

Five of the 17 transfers on this list happened in 2025 and 2026 — Victor Osimhen's move to Galatasaray, Alexander Isak's and Florian Wirtz's arrivals at Liverpool, and Morgan Rogers' and Elliot Anderson's moves to Chelsea and Manchester City. All five carry a trophy count of zero or one, not because the transfers failed, but because none of the buying clubs has completed a full season with the new signing yet. Counting those alongside a 25-year-old deal like Zidane's would mechanically drag any correlation toward zero regardless of quality, so this analysis isolates the 12 transfers with at least three full seasons on the books.

That narrower sample, spanning 2001 through the 2023 arrivals of Declan Rice and Enzo Fernández, still averages €121.9M in fee and 8.25 trophies won per player at their new club. Running a Pearson correlation across those 12 data points produces r ≈ 0.36 — positive, meaning bigger fees do trend toward more trophies, but weak. A correlation that size explains only about 13% of the variation in trophy counts (r² ≈ 0.13), leaving the other 87% down to factors a transfer fee alone can't predict: squad fit, injuries, managerial changes, and simple luck in cup draws.

Correlation Isn't Causation Here Either

Part of the weak positive signal likely runs backward. Clubs capable of paying €100M-plus fees — Real Madrid, Manchester City, PSG — are usually already positioned to win trophies before the signing even arrives. Gareth Bale's 19 trophies at Real Madrid reflect a club that was winning Champions Leagues in the years before and after his transfer, not proof that his fee alone bought that success. The data can show that big spenders and big winners overlap; it can't show which one caused the other.

Barcelona · €148M All-In, and a 'Spectacular Failure' Label

Barcelona paid Borussia Dortmund a €105M base fee for Ousmane Dembélé in 2017, with performance-linked add-ons pushing the total toward roughly €148M — a fee that, at the time, trailed only Neymar's world record. Injuries defined his six seasons at the club more than goals did; press coverage repeatedly labeled the move a spectacular failure, and Barcelona's six major trophies with him on the books undersold the price tag by most reckonings.

Barcelona sold Dembélé to Paris Saint-Germain in 2023 for around €50M, a fraction of what they'd paid Dortmund six years earlier. It read, at the time, like a club cutting its losses on an expensive mistake.

PSG · The Same Player, a Different Story

Two years after that discount move, Dembélé won the 2025 Ballon d'Or, football's individual player-of-the-year award, as the on-field leader of a PSG side built around him. The same talent that Barcelona's €148M fee couldn't fully unlock became the best player in the world at a club that paid roughly a third of that price — the clearest single case in this dataset that fee size and player quality aren't the same measurement.

Neymar · €222M, Still the World Record Nine Years Later

Paris Saint-Germain signed Neymar from Barcelona for €222M in 2017, a fee no club has come within €40M of matching since. The move was built around one target: delivering PSG's first Champions League title. Neymar won 14 trophies in Paris, but none of them was the one the fee was spent to win.

Kylian Mbappé arrived a year later for €180M from Monaco, the second-biggest transfer fee in football history. Together the two deals cost PSG €402M — more than the annual revenue of most top-flight clubs — and Mbappé himself went on to win 16 trophies in Paris across six seasons, an even better trophy count than Neymar's.

The Trophy Arrived a Year After He Left

Mbappé left PSG for Real Madrid in 2024. The following season, 2024-25, PSG won the Champions League for the first time in the club's history — without either of the two most expensive transfers the club had ever made still on the roster. It's the single starkest data point against the idea that record fees buy the specific trophy they're aimed at.

Osimhen · €75M for an Immediate Title

Victor Osimhen's €75M move from Napoli to Galatasaray in 2025 is the cheapest deal on this list by a wide margin, roughly half of what Liverpool paid for Alexander Isak the same year. It's also the fastest to pay off: Osimhen fired Galatasaray to the 2024-25 Süper Lig title and won the league's Golden Boot in the same season, delivering silverware before four of the five priciest transfers in the dataset had even taken the field.

Compare that to the rest of the 2025-26 wave. Isak's €144.5M move to Liverpool, Wirtz's €117.5M arrival at the same club, Rogers' €137.3M switch to Chelsea, and Anderson's €135.5M move to Manchester City add up to roughly €535M in combined fees, and as of this writing none of the four has produced a single trophy. Liverpool, carrying both Isak and Wirtz, finished the 2025-26 season in fifth place with no silverware at all.

The Same Caveat Applies in Both Directions

Osimhen's fast start doesn't prove cheap fees are smarter any more than Isak and Wirtz's trophy-less season proves the opposite. All five of these 2025-26 deals are still inside their first year, the same window this analysis excludes from its correlation for exactly this reason: a single season, in either direction, isn't enough data to judge a transfer by.

The data gives the transfer-fee myth partial credit and takes most of it back. Across the 12 record deals old enough to judge, fee size and trophy count do move in the same direction — r ≈ 0.36 is positive, not zero — but the relationship is too weak to call spending a reliable strategy. Paying 63% more bought clubs only about 6% more silverware on average, and plenty of individual deals run flatly against the trend: Pogba and Rice both cost more than €100M and have two trophies each, while Bale's €100M fee came with 19.

Dembélé's arc from Barcelona 'flop' to PSG Ballon d'Or winner, and Neymar and Mbappé's combined €402M failing to win PSG the Champions League it was spent on, are the two data points that undercut the myth hardest. Both suggest the same thing: a transfer fee measures what a club was willing to pay for a player's ceiling, not what that player, or that club, will actually do with him.

Part of the weak correlation that does exist may run in reverse — clubs already built to win are the ones with the resources to pay record fees in the first place, so some of the fee-to-trophy link likely reflects the buying club's existing strength rather than the individual signing's impact. Whichever direction the causation runs, the headline number holds: record fees are not the trophy guarantee the transfer market's own hype suggests.
