RIO DE JANEIRO: Brazil striker Marta laughed off comparisons with Neymar on Saturday after she scored twice in Brazil's 5-1 victory over Sweden at the Rio Olympics.

With the home fans chanting 'Marta is better than Neymar,' five-times World Player of the Year Marta led her side to their second consecutive win in front of 43,000 fans in Rio de Janeiro.

Barcelona forward Neymar carries the hopes of the home nation on his shoulders in the men's competition as they seek to win Olympic gold for the first time, while Marta will be no less key to Brazil's chances of success in the women's tournament.

"We know Neymar is our best player right now and he is fantastic, we support him and he supports us but we'll leave the comparison to the fans," Marta said. "We have Marta, we have Neymar, we have Cristiane, we're all Brazilian."

The only blip for Brazil, who have scored eight in two games after beating China 3-0, was seeing Cristiane carried off with a thigh injury after 66 minutes.

While Brazil have already sewed up a place in the next round, Marta said they would not hold back against South Africa in their next group game.

"This means we are calmer but we can't let that influence us and relax," she said. "We were delighted that we had the same performance as in the first game and that is our challenge, to keep that going all the way to the final."
