Brighton are aiming to establish themselves as a top WSL team, and the arrival of the experienced Kirby will go on a long way to achieving that.
The club's managing director of women’s and girls’ football Zoe Johnson said: "We’re absolutely thrilled to welcome Fran to the club. She arrives as one of the most decorated English footballers of all time, playing an integral role in Chelsea's recent dominance, as well as on the international stage having been a part of England’s EURO 2022 win.
"Her experience on the pitch will be just as important off it and we have no doubt that she will help us take a significant step towards our long-term targets."
