Manchester City had a comfortable three-goal lead until injury time when Geum-min Lee scored Brighton and Hove's consolation goal seconds before the final whistle.
The home side's goals came from Chloe Kelly’s corner kick which was fumbled into the back of the visitor's net 11 minutes into the game, swiftly followed by Julie Blakstad's diving header. Laura Coombs extended the lead to 3-0 with a thunderous strike on the edge of the area to seal the win 26 minutes into open play.
But there was a heavy expectation for more, as Coombs said: “Gareth [Taylor] wasn’t actually that happy at half time, he came in and said that we need to be scoring more goals, that we were giving the ball away too cheaply at times.
