Érika is an outspoken advocate of women's football in Brazil. When Brazil lost 5–1 to Germany at the 2014 FIFA U-20 Women's World Cup, she rejected misleading comparisons to the wealthy male team's recent 7–1 defeat by Germany at the 2014 FIFA World Cup. In a damning open letter, signed by 100 female athletes, she branded Brazil "a sexist and bigoted country that never believed in, accepted, or invested properly in women's football".
