Republic of Ireland international forward Ruesha Littlejohn has re-joined Glasgow City for the 2016 season.
Littlejohn has had three previous spells with City and has also played with Arsenal, Liverpool and Norwegian side IL Sandviken.
Last year, the 25-year-old was with Celtic. Capped 29 times, Littlejohn has scored three international goals.
"It's great to be back at City once again and starting out on a clean slate with new coaching staff," she said.
"However, firstly I am grateful to Celtic and all the coaching staff for helping me last season and being so accommodating with my working commitments, taking time to help with individual sessions and also to the girls that I have became friends with, I wish them all the best.
"Having talked to the international manager [Susan Ronan] she wants me pushing myself against the best players and working hard so therefore I have to be at Glasgow City."
Head coach Scott Booth took over from Eddie Wolecki Black midway through last season and guided City to their ninth straight Scottish Women's Premier League title.
"I came in and trained for two weeks before Christmas with options of going back to Norway but after the two weeks I decided it would be best to stay here," added Littlejohn.
"I enjoyed the training and feel that I can get fitter, sharper and learn a lot from Scott, as well as being able to fit in with the girls and the style of play.
"I am looking forward to getting back into the swing of things and developing more as a player and hopefully contributing to more success for the club."
And Booth added: "Ruesha has always been a player on my radar since coming to the club.
"We were fortunate that she was able to train with us recently and her ability is unquestionable. She has a winning mentality and has proved that she will work hard to break into an area of the team that is already very strong."
