Interest, yeah. But I don't have any desire to watch it or become a fan of it.
I remember watching some of the last Women's World Cup knockout stages and the quality on show was equivalent to about league 2 mens. They just aren't that good, and not as entertaining to watch. I found it quite annoying, actually, that their highest level of play was so poor.
If they got better, then yeah I'd watch them. Give me a female Real Madrid team that can play silky football consistently and I'd watch them.
I've often wondered about the future of football and other sports possibly incorporating mixed teams. I don't have a problem with men playing against women and I like the idea of the best players making the cut regardless of their sex, but I honestly don't think many teams would would have more than 1, if any, woman/women in the starting 11 currently and in modern the political-correctness society you just know there'd be rules like "no fewer than 5 females in the match squad", regardless of whether they're good enough.
Basically, I want to see quality. Women's football just doesn't come close. I guess a lack of airtime and much smaller pay packets contributes to not many young girls not seeing it as a viable career choice and pursuing it.
