Mata was born in Burgos, Castile and León. He inherited his name from his father, Juan Manuel Mata Rodríguez, who was also a footballer, playing as a forward for nearby Burgos CF in the 1980s and early 1990s. Mata was raised in his father's home town of Oviedo, Asturias. His father later acted as Mata's agent, becoming FIFA-registered in the process. In his spare time, Mata enjoys table tennis, a sport he played as a child.
