Kelly Gago scored a last-gasp stoppage-time equaliser for the Toffees in a 3-3 draw at Villa Park.
Gago had put Everton ahead at Villa Park before Georgia Mullett levelled with her first Villa goal and Kirsty Hanson put them in front in the 59th minute.
Hikaru Kitagawa levelled for Everton, but Villa quickly retook the lead from a Ruby Mace own goal. The hosts looked set for the win until Gago snatched a point with her second of the game in the fourth added minute.

"Double disappointment, maybe," said Arroyo, when asked for her feelings after the game. "First because of how you get this goal at the end, but sometimes we celebrate at the Emirates (after the) 1-1 and that's football.
"But the main disappointment was that we were not really playing with attention and the energy and intensity that we need to play for the 90 minutes."
