Before I started doing the film and when I found out I was going to be doing it, I just decided to pump up on the whole cardio stuff. Just in terms of stamina.

But we had a fantastic coach, Simon Clifford, who runs a British football youth game which teaches Brazilian techniques; which is what we wanted to incorporate into the film. And some of those things we eventually got in.

At times those skills were really hard to do because not only was I having to contend with the camera, but I was having to learn these new skills and the ball was always kind of doing what you didn't want it to do. So it got a little bit frustrating at times but we got there.

My father in the film - which we probably haven't seen in previous movies, and in British Asian movies you could probably count on one hand - he says exactly why, actually why he's frightened for his daughter. He came to this country, England, and had a bit of a crappy time.

In terms of the frustration of my character, I suppose any teenager has probably gone through that, in terms of telling their parents, I want to do one thing, and their parent says no. I think parents sometimes forget that they were children.

But I think it's also hard to get into soccer here. I think purely on a time level on television as well because of the ad breaks. It's something to do with that as well. You can't show a complete soccer match here. Which I kind of find a bit of an odd thing.

And of course in America you've got American football and baseball and all those other ball games, soccer has become a little niche that the women have kind of filled.
