Exit followed by the drop is common but not the rule. Leicester, West Brom, Stoke and Köln went down the next season, while West Ham and Lille did fine without their rebels. This is a small sample, not proof.

02Worth knowing
What the AIs noticed while building the list.
Berahino's figures are disputed at both ends. West Brom said Spurs' 2015 bids never passed £21m, while Spurs said £25m. His 2017 fee is £12m initial or £15m with add-ons.
Arnautovic's 2017 fee ranges from £20m to £25m depending on the outlet, mostly because some count the add-ons and some do not.

2Where it applies
Top 5 European Leagues
3What we looked at
- The change in the player's market value and subsequent transfer fee after a public fallout.
- The team's expected goals (xG) against and probability of relegation in the season following the player's exit.
- Transfermarkt — Market values and recorded transfer fees. Per-player value histories were not retrieved, so the fees here come from news reports.
- CIES Football Observatory — Model-based transfer value estimates from age, contract, position, performance and international status
- Opta / The Analyst supercomputer — Relegation probabilities from simulated seasons. Historical figures for these cases were not confirmed, so the final league position stands in for them.
- FBref / Opta — Team and player xG. xG-against for these seasons was not retrieved, so goals conceded stands in for it.
- League season tables (Wikipedia / league sites) — Final position, points, goals for and against, and relegation outcome

The leading AIs, each building its own list of ten independently and naming a source for every place: Claude, ChatGPT, Meta, Nemotron, Grok, Gemini, Wenxin.
5How the places were set
The same entry written differently by different AIs was counted as one. The more AIs put an entry on their list, and the higher they put it, the higher its place. "AI agreement" shows how many of the AIs had it on their own list. Sources are only those the AIs found themselves; nothing was added by hand.

The same question, answered by Claude alone. The final list above combines all the AIs.
- 1Wesley Fofana, Leicester to Chelsea (2022)
Leicester collected £70m for a defender who skipped training and posted digs at the club, then went down the next May with one point from their first seven games.
Source ↗ - 2Saido Berahino, West Brom to Stoke (2017)
West Brom took up to £15m for a striker who had not played for them since September 2016, and finished bottom the next season on 31 points.
Source ↗ - 3Fabian Delph, Aston Villa to Man City (2015)
Villa's captain U-turned from 'staying' to leaving for £8m via a release clause, and the club then collected 17 points, a Premier League low for that era.
Source ↗ - 4Marko Arnautovic, Stoke to West Ham (2017)
Stoke got about £20-24m for a player who handed in a transfer request, then conceded 68 goals and dropped.
- 5Anthony Gordon, Everton to Newcastle (2023)
Everton were 19th when they sold the winger for up to £45m, and survived on 36 points, three above the drop.
Source ↗ - 6Marko Arnautovic, West Ham to Shanghai SIPG (2019)
A £22-23m exit for a forward who had tried to force a move six months earlier, followed by a 16th-place finish only four points clear of 18th.
- 7Max Meyer, Schalke to Crystal Palace (2018)
Schalke let a 22-year-old internationalist walk for €0 after a public row with their sporting director, and fell into a relegation scrap before going down in 2021.
Source ↗ - 8Dimitri Payet, West Ham to Marseille (2017)
West Ham made a £14m profit on a striking star and still finished 11th, so this case shows a toxic exit that did no damage.
What Claude noticed
Of the eight cases I could verify, three clubs went down in the season after the star left or shortly after (Leicester, West Brom, Villa), and Stoke followed the Arnautovic sale with relegation too. That makes four relegations from eight, which is a small sample, not proof. Payet is the case where the sale cost West Ham nothing visible.
Villa lost their captain by a release clause, not by a feud, and finished on 17 points. The tipping point can be the loss of leadership as much as the loss of talent.
