Here is everything publicly known about Borja Sainz’s parents, siblings, relationship and children.
Who Is Borja Sainz?
Borja Sainz Eguskiza was born on February 21, 2001, in Leioa, Biscay, Spain. He began playing football with local club Lagun Artea before entering Athletic Club’s famous Lezama academy in 2012.
Borja later joined Deportivo Alavés and became the first player born in the 21st century to represent the club’s senior team. His career subsequently took him to Real Zaragoza, Giresunspor and Norwich City.
After an impressive 2024/25 Championship season in England, Borja joined FC Porto in July 2025 and signed a contract lasting until 2030.
Who Are Borja Sainz’s Parents?
Borja Sainz’s parents are Iñaki Sainz and María Begoña Eguskiza Palacios. Both parents supported his development from local youth football in Leioa to the academies of Athletic Club and Deportivo Alavés.
Football was already familiar within the household because Borja’s father had played professionally. His mother also followed his academy development closely and publicly discussed his early career after he made his La Liga debut.
Who Is Borja Sainz’s Father, Iñaki Sainz?
Borja Sainz’s father is former footballer Iñaki Sainz, who was known during his playing career by the nickname “Navarro.”
Iñaki played for Eibar in Spain’s Segunda División between 1991 and 1994. His experience as a professional footballer allowed him to advise Borja about academy development, competition and the challenges of building a career in the sport.
Borja has acknowledged the importance of both his father and his uncle in helping him understand professional football. However, Iñaki generally maintains a private life and rarely seeks media attention.
Who Was Borja Sainz’s Mother, Begoña Eguskiza?
Borja Sainz’s mother was María Begoña Eguskiza Palacios. She played an important role in her son’s childhood and was a visible source of support when he progressed from academy football to the Deportivo Alavés first team.
Begoña died in February 2026 at the age of 55. Borja subsequently shared a public tribute to his mother, while FC Porto and supporters of his former clubs expressed their support for the family.
The winger continued honouring her memory during his football career. He dedicated FC Porto’s 2025/26 Portuguese league title to her and later celebrated a goal against Rio Ave in August 2026 with another tribute.
Does Borja Sainz Have Siblings?
There is no reliable public information confirming whether Borja Sainz has any brothers or sisters. Interviews and official profiles primarily discuss his parents and other relatives connected to professional football.

Who Is Borja Sainz’s Uncle, Carlos García?
Borja Sainz’s uncle is Carlos García, a former professional defender closely associated with Athletic Club. García made 264 official appearances for the Bilbao club and also represented the team in European competition.
Carlos García’s career provided another important football reference within Borja’s extended family. Borja has credited both his father and uncle with helping him during his development as a young player.
Despite his family connection to Athletic Club, Borja left the club’s academy in 2017 and joined Deportivo Alavés, where he believed he had a clearer route towards senior football.
Who Is Borja Sainz’s Girlfriend?
Borja Sainz has not publicly confirmed having a girlfriend or wife. No reputable Spanish, English or Portuguese publication has reliably identified a current partner.

How Borja Sainz’s Family Influenced His Career
Borja grew up in an environment where professional football was already understood. His father’s experience with Eibar and his uncle’s long Athletic Club career provided him with practical advice about training, competition and career decisions.
His parents supported him when he joined Athletic Club’s academy and when he later chose to leave Lezama for Deportivo Alavés. That decision proved important because Borja progressed quickly and made his La Liga debut while still a teenager.
The family continued supporting him as his career took him away from Spain to Turkey, England and Portugal. Borja’s tributes to his mother in 2026 also demonstrated the importance of his family behind his professional achievements.
