Power-ranking history
Against expectation
Every Spanish top-flight match this club has played in the Primera División, scored against the odds an Elo rating gave it before kick-off. Over 94 seasons from 1928-29 to 2024-25 it has beaten them by +51.7 match points.
Season points use that season’s own scoring, two for a win before 1995-96 and three from it; the bars use match points so the whole series is comparable. The rating only starts telling you much after about 1960. Before that, knowing the era’s home-and-away split is almost as good as knowing the teams.
What the squad was worth
Total market value of the squad, EUR millions, by month; the player count beside it is the size of the priced squad.
How this is measured
Drawn as a step, not a curve: Transfermarkt reprices every squad in December and June (marked with a small tick on the axis) and revalues continuously between, so the line only moves when a real valuation changed, never by interpolation.
A month renders no value at all once the priced squad falls below 15 players, so a thin squad is never shown as a cheap one. The series is floored at July 2012 on purpose: earlier Transfermarkt totals reflect which players happened to be priced yet rather than the squad’s real worth, and are excluded rather than shown misleadingly low.
Upstream (dcaribou/transfermarkt-datasets) has been paused since July 2026, so the series ends where the source ends rather than where the season does.

Who controls the club
The entity that holds control today, one per franchise; co-controllers and minority holders are listed, never summed.
How this is measured
Exactly one control entity is recorded per franchise, so a portfolio can never count a club twice. Co-controllers and minority holders are shown as published and carry no weight in any total.
The chip names the evidence. Sourced: a primary source is linked (league, club, filing or tier-one outlet). Cross-checked: matched against the ownership-change sweep. Contested: disputed or mid-sale. Rows are reviewed weekly.
Stakes are as published, often only “majority”, and are not pro-rated. A record of control is not a claim about anyone’s intent or conduct.
Who controls the clubMember-owned (socios)
Member-owned Basque club, like Real Madrid/Barcelona; no external private owner.

The money ledger
Fees paid and received each season, and what the squad was worth once the trading is netted out.
How this is measured
Spent is the fees paid for players arriving, received the fees for players leaving, both in EUR millions by the July-to-June season of the move. A move with no fee on record (a free, a loan, an undisclosed sum) is counted, never priced: the small figure beside each total is the moves with a fee, plus those without (so 4+3 is four priced arrivals and three unpriced), and a quiet window is not mistaken for a cheap one. Wages are not here: they are estimates nobody licenses, and fees are documented.
Appreciation is the season’s change in squad value with the net spend taken out: buy 100m of players and finish 100m higher is zero; finish 120m higher and the club made 20m of players better, or the market repriced them. It needs a priced squad at both ends of the season (the same 15-player floor as the value chart), so it is blank rather than guessed for a season that lacks one.
The source has been paused since 6 July 2026, so the final row holds only the opening days of its window.
