Speaking upon the announcement of the move, Fox said: "It feels amazing to have signed here. When I think of Arsenal, I think of excellence, I think of a global organization, I think of family. I think of pushing the standards of football and especially in the women’s game. It’s a huge honour to get the opportunity to represent this club and I’m excited to get started and play in front of our supporters."
Arsenal head coach Jonas Eidevall added: "We’re delighted to bring Emily to Arsenal and I’m sure our supporters will join me in welcoming her to our club. Emily has shown impressive development over recent seasons and her strengths in both phases will make her an important addition to our squad. At international level, the experience she’s built up gives her an excellent foundation to make the transition to English football."
