Having joined us ahead of the 2023/24 season, the 28-year-old Finland international has made 55 Spurs appearances, scoring three goals.
Olga said: "I'm happy that I get to be a part of the journey that we're on. This season we've really taken steps in the way we play, our day-to-day life has been good and challenging, it's been the right place for me to become a better footballer.
"The things that we're doing on a daily basis really show that we're going to be able to compete. We just want to get better every day."
Our Head Coach Martin Ho said: "We are delighted that Olga has committed her future to the club. She is a central midfielder who gives us real energy, intensity and balance in the middle of the pitch, with the ability to impact the game box-to-box both in and out of possession.
"Over the past 12 months, we have been really impressed by her professionalism, her commitment to improving, and the way she consistently puts the team first. Olga brings a strong mentality every day, trains with purpose, and has the technical quality, work ethic and tactical understanding to keep growing within the direction we are building.
"We believe there is still more to come from her, and we are excited to continue supporting her development as an important part of our squad moving forward."
Having had spells in Finland and Denmark - competing in the UEFA Women’s Champions League with Danish side Brondby IF - before plying her trade in Sweden, Olga made the move to north London in August, 2023, and made a quick impact in Lilywhite, starting in our first six games in a run that saw us unbeaten in five, before being sidelined with an MCL injury in November, 2023.
Making her comeback in January, 2024, the midfielder provided the assist for Rosella Ayane’s injury-time winner over Sheffield United in the fourth round of the FA Cup on our journey to the competition’s final for the first time in our history.
Scoring in the opening game of the 2024/25 season at home to Crystal Palace, she went on to complete 16 appearances for us in all competitions that term, 12 in the WSL, and in her first campaign under Martin, Olga has featured in a further 19 games, netting once in our away fixture at Everton in September, 2025.
On the international stage, she has been part of Finland’s last two UEFA European Championship squads – 2022 and 2025 – and has earned 80 caps for her nation, scoring four times.
