Ellen White strike

             

They couldn't wait for this match to come round and in spells we did really well. We left it a bit late for the winner, but I felt we deserved it.Davison drilled the loose ball against the far post, Grant headed the rebound on to the bar and from that second rebound Davison fired home a 15-yard shot.With the hosts below their best, Birmingham created the better of the early openings as both midfielder Melissa Lawley and Williams sent efforts narrowly wide.Birmingham almost regained the lead on the hour, midfielder Jade Moore driving in a 20-yard effort that the diving Byrne turned past the post.Arsenal winger Danielle Carter forced Blues goalkeeper Mary Earps into a 24th-minute save from a well struck long range drive.But Arsenal were improved following their goal and went close to taking the lead when captain Steph Houghton curled a shot just wide.But a minute later, Gunners keeper Emma Byrne had to stretch to touch Williams's curling 25-yard shot on to the crossbar.And two minutes from time they made sure of victory when White rose to meet Carter's cross and loop a header over Earps and into the roof of the net.The Blues continued to edge the game and went ahead when Williams, after being fouled by defender Ciara Grant, struck in the resulting penalty.The Gunners now need only a draw from their final group game, against Bristol Academy next week, to ensure they go through to the semi-finals.But it took the home side only two minutes to draw level, and quite a goal it was following a half-cleared Kim Little corner.
