Every season, SigningLab publishes how well each club and each league turned signings into performance, signing by signing. Open and validated, with editions since 2016; the 2016–2024 editions are retrospective analyses of historical data, and from the 2025 edition onward publication follows the regular post-season window. Start with the club rankings below; the cross-league comparison follows.
Each ranking measures the share of a club's signings that performed at or above the baseline expected for the level of investment, read on minutes, performance, availability and collective contribution. A club that finds undervalued players who outperform ranks above one that spends more for the same result.
The reading is ex-ante and auditable: outcomes are compared against what was reasonable to expect before each signing. The market gets roughly one in three right; the rankings show who does better, and who does worse. To access, pick a competition and a season below for the club ranking, or open the cross-league comparison. Switch the language in the menu and the reports follow.
