Ffion joined the Bluebirds from Cyncoed in September 2020.
She is an athletic full-back, comfortable on either the left or the right side of defence. She is also a lifelong Cardiff City fan.
A highlight of her City career to date was netting her first hat-trick for the Club in February 2024.
Iain Darbyshire, Head of Women's & Girls' Football at Cardiff City Football Club: “Ffion is a really talented player, who has shown her quality during her time with us. She cares about the Club massively and has improved since joining. We’re really excited to see her develop even further and continue her successful spell at Cardiff City."
