Mared Griffiths signed her first professional contract with Manchester United Women in July 2025.

The midfielder was already a senior international, with Wales, and had made her Reds debut earlier that year, scoring twice against Wolves in the Adobe Women's FA Cup. “Yeah, I’m well impressed with myself and the family and so grateful for this opportunity from the club,” said Griffiths. After frequent involvements in the first-team matchday squad during the first half of the 2025/26 campaign, Mared joined WSL2 side Sunderland on loan for the remainder of the term.
