Treatment Of Women In Sport : Serena Voices Protest In A New Nike Advert

Tennis Star Serena Williams has voiced over a New Nike Advert protesting against unequal treatment of Women in Sports.

Speaking over a selection of images of Sportswomen in action - including controversial South African Runner Caster Semenya - Williams says: "if we want to play against men we're nuts. And if we dream of equal opportunity, delusional. When we stand for something we're unhinged. When we're too good there's something wrong with us. And if we get angry we're hysterical, irrational or just being crazy."

The advert for the sportswear manufacturer was unveiled at the oscars ceremony in los angeles on sunday night.
