I've never set out to be a spokesperson for women's equality. My experience of working with Amelie Mauresmo gave me a small insight into attitudes to women in sport and, because it was unusual for a male tennis player to work with a female coach, I am often asked about that. Working with Amelie was, for me, because she was the right person for the job, and not a question of her sex at all. However, it became clear to me that she wasn't always treated the same as men in similar jobs, and so I felt I had to speak out about that.
