She is a senior Netherlands international, and has also played for her nation’s Under-17s and Under-19s sides.
Utilised across the back four throughout the 2020/21 season, De Graaf showed her versatility during her maiden campaign with the Club, while also being defensively impressive since signing for the Foxes.
On 7 March, 2021, the Dutch full-back netted her first goal for LCFC Women in stunning fashion, hitting a rocket from upwards of 30 yards out during the 7-0 triumph over London Bees at The Hive Stadium - City's ninth league win in a row.
She played a total of 25 games in all competitions across 2020/21, including 19 league matches on the way to the FA Women's Championship title.
De Graaf remained contracted to the Club for the 2021/22 campaign after signing a new deal in July, returning to the Barclays FA Women's Super League where she spent two seasons with West Ham and has been deployed in more attacking areas, demonstrating her versatility.
She scored an extra-time goal at Tottenham Hotspur in January 2022 to seal the team's spot in the fifth round of the Vitality Women's FA Cup.
