Serena not supported like Federer due to colour: Ex-rank 1
Former world number one Billie Jean King, who won 39 Grand Slam titles, said that American tennis star Serena Williams is not supported like Roger Federer and Rafael Nadal because of her skin colour. King, who founded the Women's Tennis Association, also said, "Women also just don't get the attention, enthusiasm or the sponsorship money that the men do."
