3-0 win over Brighton on Sunday booked Arsenal’s place in the Women’s FA Cup final.
The Gunners nearly broke the deadlock in the first-half but Nikita Parris saw her header cleared off the line by Brighton’s Victoria Williams.
It only took two minutes into the second-half for the hosts to take the lead when Mead weaved her way into the box and pulled it back for Little, who smashed the ball home.
Mead got on the scoresheet herself in the 53rd minute after collecting a neat ball from Jordan Nobbs, before the forward drilled her shot into the bottom corner. Williamson rounded off the scoring in the 76th minute when she powered home a header from a corner.
Earlier on Sunday, Emma Hayes’ Chelsea led from the 23rd minute at Manchester City when Erin Cuthbert controlled a corner with one touch and then fired the ball past Karima Benameur Taieb.
Caroline Weir and Vicky Losada sent efforts off target at the other end before an 89th-minute header from Beth England, brought on just before the hour mark, sealed Chelsea’s place in the delayed showpiece.
The final takes place at Wembley Stadium on December 5.
