MONTPELLIER, June 14 ― When Brazil forward Marta scored a landmark 16th World Cup goal, she took the opportunity to promote gender equality with a special celebration.

After netting the opener from the penalty spot in Brazil's 3-2 defeat by Australia yesterday, the 33-year-old pointed to her boots, which sported a pink and blue symbol to represent equality.

Her boot sponsorship deal expired last year and the veteran striker has since refused to sign a new one, saying brands were not offering deals on a par with male football players.

Marta, a United Nations goodwill ambassador for women and girls in sport, instead opted to highlight the disparity on the international stage.

The goal made her the first player to score at five different World Cups, while her tally of 16 means she now shares the record for most World Cup goals alongside German Miroslav Klose.

"It's one more detail written in the history of women's football,” she said of the milestone goal. "I am honoured, but there's more to do at this tournament.” ― Reuters
