The exciting winger joins the club after progressing through some of the south coast's strongest development pathways, bringing with her pace, creativity and a determination to make an impact in red.

Calla began her footballing journey with Portsmouth FC Women Under-16s before joining the Southampton FC Academy in 2019. During four years in the academy setup, she progressed through the age groups from Under-16s to Under-23s, continuing to develop both technically and tactically in a high-performance environment.

She returned to Portsmouth FC Women Under-23s in 2023, where she spent the next two seasons building on that experience before making the step into senior football with Havant & Waterlooville Women during the 2025/26 campaign. Now, she begins the next chapter of her career with the Sirens.

Speaking after signing for the club, Calla said:

"I'm delighted to sign for the Sirens. The ambition and drive within the club were what drew me in, and I'm really excited for the season ahead."

First Team Manager Aaron Smith believes Calla's style of play will make her a real asset to the squad this season.

"Calla has been a breath of fresh air. She is an old-school winger who loves to compete with full-backs, and her deliveries are thought out and full of quality.

"She suits our game model and has shown that she has a tremendous work ethic out of possession. She will be an exciting player for the fans to watch."

A direct and hard-working winger, Calla's arrival adds further quality and competition to the Sirens' squad as preparations continue for the new season.

Everyone at Southampton Women's FC would like to welcome Calla to the club and wish her every success in a Sirens shirt.
