Champions Glasgow City have signed the Scottish Women's Premier League's player of the year Kerry Montgomery from Spartans.
The central midfielder joins ahead of City's opening league fixture on Sunday away to Hutchison Vale and in time for this month's Champions League quarter-final ties with Paris Saint-Germain.
"I'm very excited about the challenge ahead," said Montgomery, 26.
"This is the best place for me to be to develop my understanding of the game."
And the Scotland fringe player added: "The girls have been very welcoming and helpful so far and I look forward to getting started."
Glasgow City head coach Eddie Wolecki Black feels it is "imperative" that the squad has strength beyond its preferred starting 11.
"Having Alyshia Walker, Emily Thomson and Sarah Crilly ruled out, along with Courtney Whyte and Erin Cuthbert unavailable for the PSG game due to being on international duty, then the squad does lack depth," he said.
"Kerry was a post-season target, however decided to remain at Spartans.
"We were quickly made aware that she had a change of mind and once she became a free agent it was an easy decision.
"Kerry is tenacious, athletic and adds height to the midfield area. I believe that we have lacked the correct balance in the middle of the park and that her signing rectifies the problem.
"I look forward to working with her and wish her great success with the club."
City take on the French side on 22 March at the Excelsior Stadium in what will be their first quarter-final in the Champions League. The return leg is a week later.
