Juan Carlos Ferrero Donat (Spanish: [xwaŋ ˈkaɾlos feˈreɾo ðoˈnat]; born 12 February 1980) is a Spanish sports coach and a former professional tennis player. He was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP), achieved in September 2003.

This brief starts where responsible research should: with the source description of “Juan Carlos Ferrero” as spanish tennis player (1980-). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as spanish tennis player (1980-). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 24, 2026. The linked authority identifier is Q185722. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1980, 2003, 2002 and 2012.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
