After starting her club career at Deeside, Grimshaw moved to the local
Scottish Women's Premier League club
Aberdeen Ladies and played in their first team at 17 years old. In a five-year stint (she
redshirted in 2016) she played 65 games and scored 31 goals. In July 2020, Grimshaw signed for Italian
Serie A club
Milan, a scenario which she described as: "like a football
fairy tale". Milan finished as runners-up in both the league and
Coppa Italia, but Grimshaw was happy with life at the club and her coach
Maurizio Ganz. She signed a contract extension in May 2021. ==International career==
