About Club Power Index
Club Power Index (CPI) is the definitive historical ranking of football clubs across 139 years of professional football (1889-2025). Unlike popularity polls or recency-biased lists, CPI measures sustained dominance through statistically comprehensive, quality-focused achievements.
What Makes CPI Unique
- Statistically Comprehensive: Spans entire professional era, rewarding longevity and consistency.
- Era-Aware: Contextualizes achievements against competition depth, geography, and evolution.
- Quality-Conscious: Prioritizes major titles and top finishes; ignores participation noise.
- Living Index: Updates with new seasons, reflecting football's ongoing story.
Our Mission
Football greatness isn't a single trophy or viral moment—it's relevance across time. CPI restores proportion to debates, honoring early pioneers (Preston North End, Athletic Bilbao) alongside modern giants, judged fairly across eras.
"Greatness is not what once was. It is what continues."
Behind the Index
Built by data analysts passionate about sports history and statistical modeling. Focused on European clubs first, with global expansion planned. No fan bias—just transparent methodology treating history with the seriousness it deserves.
