Patri Guijarro's first-half brace set Barcelona on their way to a thumping 4-0 win over rivals Real Madrid in Liga F on Saturday.
Claudia Pina and Alexia Putellas were also on target as Barcelona continued their perfect start to the season, extending their lead at the top of the table.
The visitors dominated from the off, as Guijarro broke the deadlock inside the fourth minute, tapping in from Putellas' flick-on from a corner.
Cata Coll was forced into a big save to deny Alba Redondo an equaliser shortly after, but Madrid's hope was soon dented as Guijarro picked out the bottom corner with a superb long-range strike for her second.
Pina strengthened their lead six minutes before the break, clinically slotting past Misa with her low strike.
Putellas added some more gloss to the scoreline with four minutes remaining of normal time, beating the Madrid keeper with a lovely dink to bring up her 199th goal for the club.
Barcelona have won all 10 of their games, and now sit eight points clear of Madrid, who suffered their first league defeat of the campaign.
