Brooke Nunn has joined the club on loan until the end of the season.
The experienced forward travels to ML1 following a brief stint at Hibernian which followed spells at Turkish Super League side Altay S.K Women, London City Lionesses, London Bees and Arsenal.
A product of the Arsenal academy, Nunn played a part in the Gunners back-to-back WSL title victories in 2011 and 2012.
“A massive addition to the squad at this stage of the season,” Head Coach Paul Brownlie said.
“Brooke has vast experience and quality which will help with the increase of depth to the squad and provide more attacking options. After speaking with Brooke, I know she really wants to come here and make an impact, which I believe she can do.
“I’m excited about her talent and seeing if we can unlock that because, if we can, she can be absolutely brilliant for us.”
The 31-year-old has accomplished numerous titles in the women’s game, with two Women’s FA Cup and two FA Women’s League Cups complimenting her league title success.
“I’m really excited to get started here at Motherwell,” Nunn said.
“The club have a great vision and I hope I can contribute to its success. I’m really looking forward to my new challenge.”
