Glasgow City boss Eileen Gleeson has had to step down from her role as head coach, the club confirmed.
The former Ireland women's national team assistant had joined the club in November after "enabling a career break" from her employer in Dublin.
However, Glasgow City announced Gleeson would leave the club after a review on "operational business needs" decided she needed to return to her previous role.
Gleeson leaves with the club sitting top of the table after 12 matches with lead assistant first-team coach Leanne Ross placed in interim charge.
Assistant coach Keiron McAneny and goalkeeping coach Sam Devine will support Ross in the role.
Chief executive Laura Montgomery said: “Everyone at Glasgow City would like to thank Eileen immensely for her contribution to the club in her year at the helm.
"She has brought about a number of incredibly positive changes to the club and leaves us in a fantastic position, sitting top of the table after 12 games played so far.
“This is an incredibly difficult position, but Eileen kept us up to date with the situation and we are well prepared to continue positively in her absence.”
“It is with great difficulty that I make the decision to part ways with Glasgow City FC," said Gleeson commenting on the club website.
"I would like to sincerely express my gratitude to all at the club for providing the opportunity to be involved with such an iconic women’s football club such as Glasgow City.
"I wish to thank the board, staff, and players for their progressive attitude, and always striving to raise their standards during my time at the club.
"At this point I am happy to leave the club top of the league table and have no doubt that the club are well positioned to continue uninterrupted by my absence in the capable hands of Leanne Ross and an excellent support staff team.
"I wish Laura, Carol Anne, the board, staff, players, fans, and all associated with the club every continued success for the future and will always remain a Glasgow City fan #OCAC."
A club statement added: "Glasgow City can confirm that Head Coach Eileen Gleeson has had to step down from her role with the club.
"Eileen joined Glasgow City initially by enabling a career break from her employer in her hometown of Dublin.
"Unfortunately, due to operational business needs, her employer has had to review this and she needs to return to resume her previous role."
