Real Madrid

In 2020, Abelleira joined the newly established Real Madrid, where she quickly became an important young player for the club. Over the years, she developed into one of Real Madrid’s most influential players. However, during the 2025–26 season, she was unable to make any appearances due to injury. She served as the team’s second captain for the 2025–26 season and has made over 170 appearances for the club. On 12 June 2026, Real Madrid announced that Abelleira would depart the club upon the expiration of her contract, ending a six-year tenure with the team.

Abelleira was born on 9 January 2000 in Pontevedra, Galicia, to former footballer and coach José Emiliano "Milo" Abelleira Solla, and Teté Dueñas, as the youngest of three siblings. Abelleira is the godmother of her niece. Her paternal family was a traditional baking dynasty that ran the Abelleira bakery, one of the oldest businesses in Pontevedra and oldest bakeries in Spain at the time it closed in 2023, having an impact on Pontevedra cuisine, as well as being closely connected to football. Her father and brother Tomás have both played for Pontevedra CF, with Milo also having coached the club. Her grandfather's brother, Benigno Abelleira, is president and an original member of the Peña da Boina, the oldest official fan club of Pontevedra CF, and was a good friend of Camilo José Cela.

As of 2019, Abelleira was in a relationship with her former teammate Patricia Curbelo; when the couple posted about each other on social media, they received homophobic abuse, which they then shared and said they would continue to fight.
