Yago Yao was born in Abidjan, Ivory Coast to an Ivorian mother and a Spanish father. Six hours after his birth he was taxed as Spanish and, three months later, he was taken to live in Asturias where his paternal grandfather was from.
Yago Yao played solely in Spain during his career, representing Sporting de Gijón (two stints), Celta de Vigo (two, being severely injured early into his second), Recreativo de Huelva, Real Oviedo, Cádiz CF and Levante UD. In 2000–01 he appeared in 20 games in La Liga as the Galicians finished sixth, but split the 2002–03 season with two teams that met the same fate, relegation (Recre and Oviedo, one in each of the major levels of Spanish football).
Yago Yao possessed dual nationality, and went on to represent the Equatorial Guinea national team, his first cap coming in 2007 at age 28 against Cameroon. He previously appeared for Spain at youth level.
