Cholismo Lab is a fan site dedicated to Atlético Madrid.
From Simeone's tactical philosophy and the club's history, to detailed player stats, match reports, a stadium matchday guide, and quizzes to test your knowledge — we aim to deliver everything Atlético, clearly, readably, and accurately.
Whether you're just discovering Atlético or have been following them for years, we want this site to offer something for every depth of fandom.
Cholismo Lab is run solo by a Japan-based fan who has followed Atlético Madrid for over a decade.
The 2014 La Liga title, two Champions League finals, and every high and low of the Simeone era — all watched in real time. This site is the product of the knowledge and passion built through those years.
The reason this site exists is simple: to share the magic of Atlético with more people.
Accuracy is our top priority. Player data, tactical analysis, and historical facts are all verified against multiple sources before publication. If you spot an error, please don't hesitate to reach out.
