Salma Celeste Paralluelo Ayingono was born on 13 November 2003 in Zaragoza, Spain. A gifted athlete as well as a footballer, she competed at a high level in sprinting and hurdling while developing her football career. After playing for Zaragoza CFF, she joined Villarreal in 2019 and helped the club earn promotion to the Spanish top division before joining Barcelona in 2022.
Paralluelo quickly became an important attacking player for Barcelona, combining exceptional speed with direct running and an increasingly prolific goalscoring record. Across four seasons she made 131 official appearances and won numerous domestic honours as well as three UEFA Women's Champions League titles. Her final Barcelona appearance came in the 2026 Champions League final, when she scored twice against OL Lyonnes. After leaving Barcelona at the end of her contract in June 2026, she joined OL Lyonnes.
Paralluelo enjoyed remarkable success with Spain before reaching senior level, winning the FIFA U-17 Women's World Cup in 2018 and FIFA U-20 Women's World Cup in 2022. She made an extraordinary senior debut against Argentina in November 2022, scoring a hat-trick. At the 2023 FIFA Women's World Cup, Paralluelo scored crucial goals in the quarter-final and semi-final as Spain won its first world title, and she received the tournament's Best Young Player award.

Before focusing exclusively on football, Paralluelo was an elite track athlete who competed primarily in sprint and hurdles events. As a teenager she set Spanish age-group records and represented Spain internationally in athletics.
