Brazilians marveling at Marta

They share similar heavy burdens of expectation, but there is no battle between soccer stars Marta and Neymar to be Brazil's darling of the Rio Olympics - at least according to women's team coach Vadao.

Five-time World Player of the Year Marta was in sensational form as Brazil's women got off to a perfect start on the first day of competition at the Games with a 3-0 win over China on Wednesday.

Her assist on Andressa Alves second goal brought chants of "Marta is better than Neymar!" from an enthusiastic - if far from capacity - crowd at Rio's Olympic stadium.
