Data Sources

WHOSTARTED's historical lineups are calculated by our own algorithm from factual, openly licensed player data — never copied from a licensed product and never using club crests, competition logos or photos. The datasets below are credited according to their licence terms.

Some entries are additionally corrected by players who spot a mistake: every report is checked against the public sources above — never against a paid or commercial database — before anything changes, and the fix is credited to the community member who found it.
