Williams, a scorer as we lifted the trophy for the first time last season in a 4-0 win over Tottenham Hotspur, came off the bench in this year's showdown between Chelsea and United, with the London outfit leading by a single goal when she entered the fray with fewer than 10 minutes to play.
Sandy Baltimore had given the Blues the advantage with a penalty on the stroke of half-time, but the fightback was not to be for Marc Skinner's side, as Sonia Bompastor's team scored twice more in the closing stages; Catarina Macario heading home before Baltimore struck another.
