Sources & References

How to evaluate our sources

We prefer primary sources for laws, schedules, results, official statistics, and career announcements. Analysis and training suggestions are editorial interpretation, not official guidance. Individual articles should link to the sources that support their specific factual claims; this general directory is not a claim that every article has been checked against every source listed.

Useful primary sources

• IFAB Laws of the Game for the official Laws of Association Football.
• FIFA for international competitions, regulations, and official announcements.
• UEFA for European competitions and official competition information.
• Official national association, club, league, and competition websites for roster, schedule, match, and career information.

Attribution and limitations

Sources can change, be corrected, or use different statistical definitions. We aim to identify the season, competition, and relevant context when figures are discussed. Third-party reporting may be useful background but is not a substitute for an official record. If you spot a missing or incorrect source, contact us through the Contact page.
