Poppy started her career at Cardiff City in her native Wales, making nine appearances before joining Plymouth Argyle in 2020. Soper soon established herself as the Pilgrims' number one and would go on to make 31 appearances for Argyle, including one against Town, before her form saw her earn a move to Chelsea in February 2022.

 

Poppy spent six-months at Kingsmeadow as part of the Chelsea side that won the Women's Super League title before joining Charlton on a two-year deal in August of last year, with her debut coming in a Conti Cup clash with Lewes in October.

 

Internationally, Soper has been called-up several times for Wales at senior level but has yet to debut for her country.
