Women soccer players in Spain crossed their arms for about 30 seconds at the beginning of a match on Sunday to demand the signing of the sport's first collective agreement in the country.

The 22 players of Real Sociedad and Barcelona stood with their arms crossed after the initial kick-off at the inaugural Spanish Super Cup in the city of Salamanca. Fans applauded the protest, which was joined by the bench players from both teams. The deal for the collective agreement was struck in December but it hasn't been made official yet.

The women went on strike for a round of league matches in November over wages and working hours.
