Anssumane "Ansu" Fati Vieira (born 31 October 2002) is a professional footballer who plays as a left-winger for Spanish club Barcelona. Fati was born in Guinea-Bissau but represents Spain internationally.
Born in Guinea-Bissau, Fati moved to Herrera, Seville with his family at the age of six, when his older brother Braima signed for Sevilla. Another brother Miguel is also a footballer.
Fati was originally eligible to represent Guinea-Bissau at the international level but did not represent the nation of his birth at any level.
After his debut in La Liga, the Spanish Football Federation (RFEF) showed interest in him, with Diario AS reporting that the Spanish government had set its sights on granting Fati citizenship with a view to including him in the squad for the 2019 FIFA U-17 World Cup. He is also reportedly eligible for a Portuguese passport through his grandparents' birth in colonial Portuguese Guinea.
Fati was granted Spanish citizenship on 20 September 2019, renouncing his Bissau-Guinean citizenship. He was called up to the Spanish under-21 team on 11 October 2019, following an injury to Carles Pérez. Fati made his debut for the Spanish under-21 team on 15 October 2019 against Montenegro.
