Alberto Costa, whose full legal name is Alberto Oliveira Baio, is a Portuguese footballer from Santo Tirso. Although the FC Porto defender keeps much of his private life away from public attention, several reliable details are available about his girlfriend, biological father, stepfather and family background.
Alberto Costa’s Family Background
Alberto was born on 29 September 2003 in Santo Tirso, Portugal. FC Porto’s official profile describes him as having been born into a family of FC Porto supporters. This family connection made his eventual move to the club especially meaningful.
His upbringing also explains why he plays under the surname “Costa,” even though it does not appear in his full legal name. According to the Diário de Santo Tirso, Alberto adopted Costa as his professional surname to honour the stepfather who raised him from childhood.
Who Are Alberto Costa’s Parents?
Football databases including Zerozero identify former footballer Suleimane Baio as Alberto Costa’s biological father. Baio was born in Guinea-Bissau and played as a forward during his football career.
However, publicly available reporting indicates that Alberto was principally raised by his mother and stepfather. The names and occupations of his mother and stepfather have not been reliably disclosed by major sources.
Why Does Alberto Use the Surname Costa?
Alberto’s legal surname is Baio, but he chose to be known in football as Alberto Costa. The decision was a personal tribute to the stepfather with whom he had lived since childhood and who played an important parental role in his upbringing.
This makes “Costa” more than a sporting name. It publicly acknowledges the man Alberto considers an important father figure, while his legal name preserves the Baio surname associated with his biological father.
Who Is Alberto Costa’s Father?
Available player databases list Suleimane Baio as Alberto’s biological father. Baio is a retired Guinea-Bissau-born footballer who played mainly as a striker.
Alberto’s stepfather was the person who raised him from an early age. Although local reporting confirms this relationship, dependable publications have not revealed his stepfather’s complete identity. It is therefore important not to confuse Alberto’s biological father with the stepfather he honours through the Costa surname.
Who Is Alberto Costa’s Mother?
Alberto Costa has not publicly identified his mother in widely available interviews, and reliable reports do not provide her name or profession. What is known is that his parents and wider family continued to support him during his move abroad.
While discussing his time at Juventus, Alberto explained that he moved to Italy with his girlfriend and received visits from their parents on some weekends. This suggests that his family remained closely involved during an important period of adjustment in his career.
Does Alberto Costa Have Siblings?
There is currently no reliable public information confirming whether Alberto Costa has any brothers or sisters. No sibling has been consistently identified in official profiles or established Portuguese sports reporting.
This does not necessarily mean that he is an only child. It simply means that any siblings he may have remain outside the public spotlight.
Who Is Alberto Costa’s Girlfriend?
Alberto Costa has confirmed that he has a girlfriend. In a March 2026 interview about his transfer to Juventus, he said that his girlfriend accompanied him when he moved to Italy.
Her name and personal background have not been reliably disclosed. Alberto appears to protect her privacy, so social-media speculation should not be presented as confirmed information.
Is Alberto Costa Married?
There is no reliable evidence that Alberto Costa is married. Public reporting describes his partner as his girlfriend rather than his wife.
Does Alberto Costa Have Children?
As of September 2026, Alberto Costa has not publicly announced having any children. No credible sports or biographical source identifies him as a father.
How His Family Supported His Football Career
Alberto began playing football around Santo Tirso before entering Vitória de Guimarães’ academy at approximately ten years old. His development required years of commitment from both the player and the relatives responsible for supporting him.
The family’s connection to FC Porto is particularly notable. Alberto grew up in a household of Porto supporters and later described joining the club as the fulfilment of a childhood dream. His return to Portugal also brought him closer to the family network that had supported him throughout his development.
