Marieanne Spacey, one of the most successful English female footballers, has completed a surprise move from Arsenal to Fulham.
Spacey, who has won 91 England caps, helped The Gunners clinch a second successive AXA FA Premier League title in April.
The 36-year-old striker has been with Arsenal since 1994, more recently combining her playing role with that as the club's Development Officer.
However, she has now switched from north to west London to join arch-rivals Fulham Ladies - England's only professional women's football team - on a free transfer.
Spacey said: "Obviously it was a very difficult decision to leave Arsenal after such a long time.
"Earlier on last season I had considered retiring but I had never expected this kind of opportunity to arise.
"The chance to play professional football has rejuvenated my enthusiasm and I feel I have a lot to offer Fulham Ladies."
Fulham claimed the FA and League Cups last season and will face Spacey's old Arsenal side in the Premier League for the first time next season, having risen spectacularly through the leagues since formation only nine years ago.
Ladies team Manager Gaute Haugenes said:
"I am very pleased to welcome Marieanne to Fulham ladies. Her footballing credentials are excellent and I'm sure that she will be a great addition to the squad.
"Last season we achieved great success on the pitch and our ambitions for this season are equally high.
"Joining the top flight of ladies football for the first time will bring many challenges. I believe that Marieanne's experience and commitment to the game will benefit the team. Our aim is to continue to realise the ambitions of our chairman."
