Arsenal Ladies completed the double FA Cup defeat of Cardiff City on Sunday with a 4-1 win following the men's 2-1 victory a day before at Highbury.
Cardiff started brightly but Arsenal soon got a firm grip on the game and after 10 minutes goal machine Julie Fleeting put her side ahead with a glancing header from the first corner of the match.
Although Arsenal dominated possession and were denied their second after hitting the crossbar, Cardiff drew level midway through the half after a counter-attack saw Arsenal opened up at the back.
In the second half Arsenal's finishing showed a marked
improvement and, after some good movement down the left by Kelly
Smith, her cross found Fleeting in space at the back post. The
Scotland striker had time to calmly chest down the ball and slip it
past the advancing keeper for her second of the game.
It was another corner which led to Arsenal's third in the 65th minute. Sanderson's delivery was met by Faye White at the back post and the Arsenal captain slotted in the rebound after her initial header was saved by Cardiff's keeper.
Arsenal's victory and passage through to the Fifth Round was sealed five minutes later when Yankey rounded two defenders on the edge of the box and fired an unstoppable shot from 18 yards into the top right hand corner.
