Putellas was born in Catalonia's Mollet del Valles, grew up watching Barcelona matches, and idolised Andres Iniesta, Rivaldo, and Ronaldinho. After stints at Espanyol and Levante, she returned to her childhood club in 2012, launching a 14‑year spell that yielded 38 trophies, 10 league titles and four UEFA Women’s Champions League crowns. She won back‑to‑back Ballon d’Or awards in 2021 and 2022 and helped Spain lift the 2023 World Cup before finishing runners‑up at Euro 2025.

In July, Putellas left the elite for the nascent London City Lionesses, eager to test her limits outside the Champions League. She admits the move demands a new mindset, but says her competitive drive comes from a desire “to keep going, never stop and be as good as I can.” While learning English and adapting to London life, she remains focused on the WSL’s challenges, joking that her first press conference felt “a little scary” and that she prefers to stay away from cameras.

The transfer, endorsed by billionaire owner Michele Kang, has sparked a flood of social‑media support and a mural in her hometown. Fans anticipate a season that could redefine her legacy beyond Barcelona.

London City, founded in 2023, offers a fresh competitive arena where Putellas seeks to refine her tactical acumen and inspire a younger generation of Spanish players.
